srcFiles = dir('D:\study\iccit_confr\mono\*.jpg');  % the folder in which ur images exists
for i = 1 : length(srcFiles)
    filename = strcat('D:\study\iccit_confr\mono\',srcFiles(i).name);
    I = imread(filename);
    %figure, imshow(I);
     I2 = imcrop(I);

   disp(u)
   csvwrite('test.csv',u)

I have LBP function file. By this code only last result stored in CSV file. plz, help by giving a code for solving this.

You need to change the filename for each loop iteration, e.g.:
fnm = sprintf('test_%04d.csv',i);
csvwrite(fnm,u)
Otherwise you are simply overwriting the same file on each iteration.
