Plsss help me to solve this error???

Traindatabasepath='E:\PROJECT2\original\appleleaves\ceder';

for ii=1:size(Trainfiles,1)
    if not(strcmp(Trainfiles(ii).name,'.')|strcmp(Trainfiles(ii).name,'..')|strcmp(Trainfiles(ii).name,'Thumbs.db'))
        Trainnum=Trainnum+1;
    end
end
imgccount=1;
for imgn=1:Trainnum
img=imread(strcat(Traindatabasepath,'\',num2str(imgn),'.jpg'));
% imshow(i);
% j=imresize(i,[256 256]);
% figure,imshow(j);
[r c]=size(img);
%global feature extraction

Your images are not all the same size.

Note:

[r c]=size(img);

is probably a mistake. You do not use r or c so you might as well remove the line.

At that point in the code, img is an RGB image, so it has 3 dimensions. When you ask for only two outputs, the second output is number of columns times number of color planes -- the product of the outputs from size() is always equal to the number of elements in the array.
