I want to create the .mat file in which I need to store the Colour images and corresponding each colour image I need to store 4 histograms in row form. Can any one help me with code how to store color image and corresponding histogram in row form?

Make a 2D array of 1024 column by 50 rows
output = zeros(totalNumberOfImages, 1024); % Initialize
for imageNumber = 1 : totalNumberOfImages
% Compute the 4 histograms...
% Now save them
output(imageNumber, :) = [count1, count2, count3, count4];
end
do for all images, then save output (or whatever you want to call it) to a mat file
save(matFullFileName, 'output');

I have tried your code but I am getting error. So tell me where I went wrong. I want to also store the color image along with 4 histograms. So tell me how to do that? Currently for checking I have Used 5 as the count instead 50. The code is as below:
output = zeros(5, 1024); % Initialize
for imageNumber = 1 : 5
% Compute the 4 histograms...
Image=imread(strcat('Temp\',num2str(imageNumber),'.jpg'));
Image=imresize(Image,[256 256]);
count1=LRBP(1,Image); %1st Histogram
count2=LRBP(4,Image); %2nd Histogram
count3=LRBP(16,Image); %3rd Histogram
count4=LRBP(64,Image); %4th Histogram
% Now save them
output(imageNumber, :) = [Image,count1, count2, count3, count4];
end
save('Hmat.mat', 'output');
Error is as follow:
??? Subscripted assignment dimension mismatch.
Error in ==> Hist_mat_t1 at 11 output(imageNumber, :) = [count1, count2, count3, count4];
??? Subscripted assignment dimension mismatch.
Error in ==> Hist_mat_t1 at 13 output(imageNumber, :) = [count1, count2, count3, count4];
??? Error using ==> horzcat CAT arguments dimensions are not consistent.
Error in ==> Hist_mat_t1 at 13 output(imageNumber, :) = [Image,count1, count2, count3, count4];

Sorry but I am not getting this point: How in .matfile all images and 4 histograms will be saved since we are creating it after the for loop, so it will store the image and histograms of the last image in .matfile??? I mean while running entire for loop all computation will be performed but only single image and its 4 histograms will be saved in .mat file. So please explain me this. Please help me for understanding this.
Thanks a loot!! Image Analyst please resolve my error.

You stuck image at the front, which is a 256x256 array. You can't stitch it horizontally with a 5x1024 array because the numbers of rows don't match. Why do you want to store the image in the mat file anyway? If you did, you'd have to do Image(:) to get it into a row vector, but I don't recommend it since you already have the images stored on disk. If you want you can store the filenames in the same mat file with a different variable name.

Just don't save the images, like I said. I'll be in a meeting with the Mathworks people for the next 2 hours so I won't reply until after that.

Sorry!! I just Cleared my doubt today. So i don't need to store image in .matfile. It was my misunderstanding. But tell me what should I do to resolve the error which i told you yesterday. How should I modified your code so that i won't get that sunscripted dimension mismatch error. Thanks for your response. I was online when I commented yesterday your comments delivered late. Thanks!!! Please guide me.

And I want to understand that we are saving output in .matfile at the end of the for loop so in .matfile there will be only last 4 histograms of image will be there?? This is what i interpreting from your code. So please clear my this doubt how 4 histograms of all images will be stored in .matfile. Please help!! I don't have much knowledge of matlab so i m asking. Thanks in advance!!!

Why do you say that? Notice that output has totalNumberOfImages rows, so every row in the matrix is 1024 elements long, which is the 4 histograms. So you will have every image's histograms in there, not just the last one.
You will not have that error anymore if, like I recommended, you do not try to save "Image" in the row.

Image Analyst still I am getting this error. I don't know why? ??? Subscripted assignment dimension mismatch.
Error in ==> Hist_mat_t1 at 12 output(imageNumber, :) = [count1, count2, count3, count4];
Check and tell me where I should make change??
output = zeros(5, 1024); % Initialize for imageNumber = 1 : 5
% Compute the 4 histograms...
Image=imread(strcat('Temp\',num2str(imageNumber),'.jpg'));
count1=LRBP(1,Image); %1st Histogram
count2=LRBP(4,Image); %2nd Histogram
count3=LRBP(16,Image); %3rd Histogram
count4=LRBP(64,Image); %4th Histogram
% Now save them
output(imageNumber, :) = [count1, count2, count3, count4];
end
save('Hmat.mat', 'output');
Image is being resized into 256X256 by the function LRBP which returns the histogram. Guide me. Thanks for response!!!!!

I ran your code it is working fine. According I changed your previous code and tried to run it but now it is giving me error for the function LRBP which returns the histogram. The modified code is:
clc; clear all;
output = zeros(5, 1024); % Initialize
for k = 1 : 5
% Compute the 4 histograms...
Image=imread(strcat('Temp\',num2str(k),'.jpg'));
[pixelCount1, grayLevels1] = LRBP(1,Image);
[pixelCount2, grayLevels2] = LRBP(4,Image);
[pixelCount3, grayLevels3] = LRBP(16,Image);
[pixelCount4, grayLevels4] = LRBP(64,Image);
% Stitch together and stick into one row of the array.
output(k,:) = [pixelCount1', pixelCount2', pixelCount3', pixelCount4'];
end
save('Hmt.mat', 'output');
Error is as follows:
??? Error using ==> LRBP Too many output arguments.
Error in ==> ImT at 8 [pixelCount1, grayLevels1] = LRBP(1,Image);
Since LRBP is LBP on radon transform so I am applying radon transform on each block of the divided image then applying LBP on each block so corresponding to each block I have the histogram and I am merging this histograms by your code for that and getting final histogram. So LBBP is that histogram (After concatenating). I am displaying the Output of the LRBP as follow (All 4 Histogram output)

>> SO Now what should I do??? since I am getting output of LRBP histograms as above. I tried using imhist on the LRBP histogram but it makes all the values to zero and only last values has some number. So I can't use imhist.
Thanks Image analyst for your continual support but again im stucked. So please guide me.
Thanks!!!!!!!!!

Put the cursor in LRBP and type control-d and tell me what the function line says. It might look something like
function [out1, out2] = LRBP(input1, input2)
but it probably looks like
function out1 = LRBP(input1, input2)
and provides only 1 output but you are expecting it to provide 2 outputs.
radha

Means I should type control-d in command prompt after putting cursor in LRBP function???
radha
2014-3-8
I m not getting where to type control-d. I tried on command prompt but it gives me error. No such variable. And in the file of the LRBP but nothing happens. So please explain how to do that so that I can check what you want and let you know.
WE can proceed further.

Put the cursor right over the word "LRBP" in your text editor, then click. You will get a veritical blinking cursor between some letters of that word. Then type control-D or right click and select Open LRBP from the pop up context menu. It should bring you to LBRP source code. Then tell me how it's defined.

LRBP function I have created and defined. It takes the number of blocks as first input and image as second input. Then based on number of blocks given it divides the image into that number of blocks and apply radon transform on each block then lbp on that radon transform. Thus Each block has histogram which is then merged into single histogram. Basically I am using spatial pyramid with level 4 so level one has one grid i.e. entire Image, level 2 has 4 blocks, level 3 has 16 blocks, level 4 has 64 blocks. So there are 4 cases in LRBP ie. no_of_blocks = 1,4,16,64. thus corresponding to these 4 level I m storing these histogram(i.e. after merging histograms of all blocks) in .matfile. Hence 4 histograms. Source code is here:
function Hist = LRBP( no_of_block,Image )

I am implementing LRBP algorithm. So I declared function instead of copy pasting the code for each level of spatial pyramid for getting the merged histogram. So Now You say what went wrong. For dividing image into blocks code I have taken form matlab central only.
Thanks a lot for your support. Guide me. Thanks!!!!

Look how you defined it:
function Hist = LRBP( no_of_block,Image )
Notice there is only one single output . Now, look how you're calling it:
[pixelCount1, grayLevels1] = LRBP(1,Image);
You're expecting two outputs , not one! So what's called Hist inside LRBP gets assigned to pixelCount1 in the main program, but LRBP does not pass back any second argument so there is nothing to stuff into grayLevels1 . That's why it says there are too many output arguments. If you want grayLevels1, you need to pass something out that can be put into grayLevels1.
radha
2014-3-8
So what should I put there in grayLevels1??? OR I change it like this???
[pixelCount1]=LRBP(1,Image);
But this will have any impact on the output?? Sir, you suggest what should I do???
Image Analyst
2014-3-8
Just don't accept grayLevels. Or send it out. Either way. You don't need it in your calling code so I'd just leave it off when you call it.
pixelCount1 = LRBP(1,Image);
radha
2014-3-8
Sir, I tried using
[pixelCount1]=LRBP(1,Image);
But I am getting error of
??? Subscripted assignment dimension mismatch.
Error in ==> ImN at 14 output(k,:) = [pixelCount1', pixelCount2', pixelCount3', pixelCount4'];
So I need to pass something there in the grayLevels1.
So How I will get grayLevels1 value?? Guide me sir.
Thanks a Lott!!!! Guide.

You need to step though this in the debugger. Are all PixelCountn 1024 rows by 1 column wide arrays? If they're 1x1024 instead of 1024x1 then get rid of the transpose ' operator. What are the sizes of them? What is the value of k? Just go through the normal debugging steps.

Sir, I checked in workspace the values of pixelCounts these are of the size 1X59 so I removed transpose operator but it is giving again the same error.
??? Subscripted assignment dimension mismatch.
Error in ==> ImN at 14 output(k,:) = [pixelCount1, pixelCount2, pixelCount3, pixelCount4

];

Code is:
clc;
clear all;
output = zeros(5, 1024); % Initialize
for k = 1 : 5
% Compute the 4 histograms...
Image=imread(strcat('Temp\',num2str(k),'.jpg'));
pixelCount1 = LRBP(1,Image);
pixelCount2 = LRBP(4,Image);
pixelCount3 = LRBP(16,Image);
pixelCount4 = LRBP(64,Image);
% Stitch together and stick into one row of the array.
output(k,:) = [pixelCount1, pixelCount2, pixelCount3, pixelCount4];
end
save('Hmtt.mat', 'output');

Image Analyst what should I do now?? How can I get the value of grayLevels1 in LRBP??? Since As I told you the above code is giving me error of subscripted dimension mismatch at the line below.....
??? Subscripted assignment dimension mismatch.
Error in ==> ImN at 14 output(k,:) = [pixelCount1, pixelCount2, pixelCount3, pixelCount4
though I removed transpose operator.
Please help me.
Thanks a lot!!!! But I don't know how to deal with this now. Why subscripted dimension ??
Else How should I modify LRBP so as it return two outputs...
Please help me to finish this work of .matfile.
Thanks in advance!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Image Analyst I have tried by using grayLevles as output with the value = 59 in LRBP since 59 is total number of values in each LRBP histogram. code is:
clc;
clear all;
output = zeros(5, 1024); % Initialize
for k = 1 : 5
% Compute the 4 histograms...
Image=imread(strcat('Temp\',num2str(k),'.jpg'));
[pixelCount1, grayLevels1] = LRBP(1,Image);
[pixelCount2, grayLevels2] = LRBP(4,Image);
[pixelCount3, grayLevels3] = LRBP(16,Image);
[pixelCount4, grayLevels4] = LRBP(64,Image);
% Stitch together and stick into one row of the array.
output(k,:) = [pixelCount1, pixelCount2, pixelCount3, pixelCount4];
end
save('H.mat', 'output');
??? Subscripted assignment dimension mismatch.
Error in ==> ImLast at 14 output(k,:) = [pixelCount1, pixelCount2, pixelCount3, pixelCount4];
Still I am getting the subscripted assignment mismatch error.
So sir, please guide how I should resolve this subscripted dimension mismatch error. Why subscripted dimension error is coming every time I run??
Please solve this error. Thanks sir!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thanks a lot!!!! Help me this last point of .matFile.

Image Analyst I have understood now why I am getting subscripted dimension mismatch error.
Can you noe just help me to resolve small thing.
In case of imhist in your program working fine because the pixelCounts for them are displayed in this form. Given below....
1
2
3
4
5
like this.
And in case of LRBP pixelCounts are displayed like this:
columns 1 to 7
1 2 3 4 5
I this form.
That's Why I am getting subscripted dimension mismatch as error. This what I tried to find out cause of the error.
Now can you please help me to guide what should I change??
So that This error will be resolved.
radha

Can you just tell me how to change pixelCounts display and saving method of the LRBP to be displayed and stored like imhist.
Then error will be resolved.
radha

I am on the way of completion.
Please help.
Thanks!!! Please reply I am in tension.

Can you attach any m-files and data needed to run your program? I might be able to get to it this afternoon.
radha
2014-3-9
yes sir!!! Sure.
I am attaching all the files needed to run my program. If you want then I can also send ppt of LRBP algorithm as well.
Thanks a lott.!!!!!! I am really thankful to you!!!!!

First I am attaching the LRBP then lbp and getmapping..
Then attaching the demo file for single image matching. I have to get the input sketch image by user then get LRBP histogram at each level and compare these sketch image histograms with the LRBP histograms of color image at each level stored in .matfile.
But currently since .matfile is not created so I n demo matching is performed with respect to single image. If match is found then display message saying person present in database otherwise not present. PMK is distance used for comparing the LRBP histograms at each level.
I am using CUHK database for sketch images and corresponding photo images for this project. Basically it is used when eye-witness is only proof. So sketch will be drawn by artist and it is given as input to my project then there is criminal database having the face photo which is used for matching sketch with photo if match found the disply that message if not then that message. For this I am implanting LRBP algorithm.

Images are not being uploaded because it is giving me error !!!
No more then 10 file upload..
Wait for 24 hours.
So I am not able to send you th sketch and photo images.

If it's going to be a ton of work then I won't be able to help. I'm expecting like 5 minutes or less to find the error and fix it. If it gets more involved than that then I will just have to pass. You can zip your files together into a single zip file.
radha
2014-3-9
Okay. I will zip and send you.
Sir I explained indetail so that you have idea of what I am doing.
All these files are needed for running the .matile code.
So I am attaching with the your code of .matfile which I stored in .m file along with all other files.
Thanks for your help!!! I hope my error will be resolved.!!!
Thanks a lot!!!!!!!!!!!!!!!!!!!!!!
radha

Sir you only have to resolve my subscripted dimension error. Rest thing I know how to do it.
Sir the file name ImLast is the file where your code of the .matfile is there. To run this you will need three files LRBP,lbp and getmapping.No need to have PMK.
Sir just resolve my .matfile error in the file ImLast.m
Thanks A LOOTTT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
radha
2014-3-9
I is saying remove one or more files. So removed previously attached files.
Still not able to upload..
Error
radha
2014-3-9
Now uploaded successfully.........................
Sir Now as i explained you can use the file Imlast.m which in turn uses the LRBP,lbp and getmapping files. You here just need to use photo images only. So You can use any photo image.
Thanks a lot!!!!!!!!!!!!!!!!

Sir, will you now solve this and reply me the solution???
Because for this error I am totally dependent on you, since I have tried at my level best and no other helping me.
Please give me some positive response.
Thanks!!!!
Please reply me whatever you perform for this. So I can decide what should I do???
radha
2014-3-10
Sir, my intension is not to get every thing done by you. I have done 80% work. Only this last 20% work of .matfile is remaining.
So please just solve .matFile error.
Thanks!!!!!
Please give me response whether you are going to do or you don't have time.
Please reply. I am waiting sir........................
Thanks a lot!!!!!!!!!!!

Probably not until tomorrow night. If you solve it yourself earlier let me know so I don't waste my time.
radha
2014-3-10
Okay, sure sir....
I am trying my best....
Let see...
I will tell you if and only if I will succeed in solving it.
Otherwise you will have to help.
Thanks!!!!

Sir, can you just tell me whether we can store large values in the array created using zero. such large like 29366.
Because I thought due to this I am getting subscripted dimension mismatch. so
Just tell me can we store such large values in array of output created using zero????????????
Thanks!!!!!!!!!!!!!!!
radha
2014-3-10
Sir I tried you clear first thing Whether pixelCounts1 and pixelCounts2, etc.. It should have single value or it should be array.
Because I think if it should be single value then I am getting dimension mismatch error, since pixelCounts1,pixelCounts2, etc are returning 1X59 arry.

Sir I tried small script as below..
clc;
clear all;
out=zeros(5,1024);
for i=1:5
out(i,:)=[1 2 3 4];
end
save('T.mat','out');
But for this I am also getting the dimension mismatch error. So how to solve this for small code.
I think there is error in the code.
what do you think sir????
Can we achieve the our aim for storing in row form .matfile with this code??? For imhist it is working fine. But why not for LRBP????
Please help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thank you sir!!!!!!!!!!!!!
radha
2014-3-10
Shall we able to solve this error???
Sir I tried but not able to solve.
I need to finish by this Friday.
So if we can't solve this then there is any other alternate way to store in row wise form.
If yes then tell me I will try that....
I tried a lot sir because deadline is near...
I have to complete this...
So please guide me....
thanks for your continual response!!!!!!
Thanks a lot!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

In out(i,:)=[1 2 3 4]; the right hand side needs to be 1024 elements long, not 4. If you have 4 histograms of 256 elements each, then it will be 1024 elements long.
radha
2014-3-11
Exactly I had not changed that 1024 that is why I was getting error. Because my histograms has only 59 values. So not getting done my .matfile.
Now it's working fine.
Sir I am bit late to share my happiness because I was running my entire project.
It is good news for me that I have completed my project. I am very happy.
I don't know how much to say thanks to you. Without your help of my project would not be completed within deadline.
Sorry I disturbed you lot....
But Thanks a Lottttttttttt Image Analyst!!!!!!!!!!!!!!
Now I am developing GUI.
Thanks again....
You played very important role for my project. I never forget your help. Because only this .matfile work was left and you helped me to do that.
Again Thanks a Loootttt!!!!!
