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.

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.

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.

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
