typically scientific cameras are black and white or grey scale and so rather than each pixel having a red, green and blue value to make a color image, only a single value is obtained.
I am working on the code with some image took from the lab.
The files are in *im7 format.
For this image, I am trying to find a enclosed area of the bubble.
For instance area of 1 & 2 of the image.
So I made a code that works on normal jpg files (which is RBG type)
For single image a=imread ('rose.jpg'); % read image
b= rgb2gray (a);
c= im2bw(b)
regions1and2 = imclearborder(~c);
area = bwarea(regions1and2);
for multiple images
path= 'F:\Thesis data\'
file= dir([path '*.jpg']);
n_file=length(file); count number of files
x = 1:1:10
for i = 1:n_file
temp = imread([path file(i).name])'
temp2 = rgb2gray (temp)
temp3 = im2bw(temp2)
temp4 = imclearborder(~temp3);
area(i) = bwarea(temp4);
end
plot(1:n_file,area);
xlabel('Time','FontSize',10)
ylabel('area','FontSize',10)
However, as this code is only works with the normal image with RGB info, I found out that I can not use this. I thought of change my image to jpg, but I realiesed this was stupid because this way the image becomes less clear.
Note: what im7 file provide as follow:
readimx is a special code that reads the information of a single im7 file.
So here is a actual question for this issue,
Is there a way to use some of my current code to read im7 file and work out the enclosed area of the image?
