Hi i am working on my project on image processing. In that i need to divide an image into overlapping blocks and then apply svd i.e. singular value decomposition to each block. Any help in this context is appreciated.

See the FAQ for code on NON-overlapping blocks. http://matlab.wikia.com/wiki/FAQ#How_do_I_split_an_image_into_non-overlapping_blocks.3F

If that doesn't work for you then you can have overlapping by the window size minus 1 if you use most functions, or a custom function if you use nlfilter(). If you use any amount of overlap other than 0 or 1 pixel, please explain why you need to do this, since I have doubts as to whether you actually need to do that.

ok....thanks for such a wonderful explaination. i want to do it with overlapping. But i have one doubt, in my base paper which i am implementing in matlab the authors do not mention about how many pixels needs to be considered for overlapping. They just mention divide image into overlapping blocks and apply svd to each block. can u enlighten this context?
