I have divided image into 30 blocks and obtained histogram of each block using LBP algorithm, i do not know how to store them separately and merge all histogram to get the single histogram?I want code for merging and saving each histogram of block.

Please just help me to concatenate all histogram of an image into single histogram., and how to create .mat file in R2011a version of matalb??

I do not have any idea about merging/concatenation of histograms. so your help is of great importance to me. I am doing project on this so I expect that you reply as son as possible.

在 MATLAB Online 中打开

Create a mat file with the save() function. You can attach your actual image with the paper clip icon if your code can only work with that kind of image. To add histograms, do this

sumHist = hist1 + hist2;  % Must have same number of bins.  hist1 can be sumHist if you want.

Can you please also help me for implementing the spatial pyramid matching kernel?? I mean I don't have any idea about its implantation that how I should proceed?? So please help me for these two implementation i.e. spatial pyramid matching and one I already asked about .mat file in above comment.

Thanks in advance. You really helped me. Now just I have these two things need to implement. I hope you also help me for that as well.

Hi there. I'd suggest to have the histograms concatenated via Matlab CAT command. masterHist=cat(1, hist1, hist2,...hist30);

I believe a similar scheme is proposed for face detection in "Face Description with Local Binary Patterns: Application to Face Recognition", http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=1717463
