Thread Subject: About Image Processing

Hi everyone,
I'm new to MATLAB and working with MATLAB as a part of my project, my query is, is there any function to segment an image into square blocks using IPT of matlab? and can we write code for the particular block? Hoping for reply..
thanx in advance

What do you mean by segment? The usual "image processing" definition
for "segment" doesn't really make sense in the context that you used
it. What do you really want to do? Do you want to chop the image up
into separate arrays? Do you want to do some kind of processing that
moves a window in discrete jumps and processes the image block by
block? Maybe you should look into the bsxfun() function.

Maybe you are looking for BLKPROC (BLOCKPROC in newer version) ?

Sir,
I think I'm wrong in usage of the terms. Actually, I meant segmentation in the sense dividing the image into many rectangular cells and programming for every cell.
I'm using this interface for a website design and I want to link "cell in one image to the cell in another". Is this chance valid in Matlab using Image processing tool?

I'm not sure what this means "I want to link "cell in one image to the
cell in another""
but did you look up blockproc like Ashish suggested?
I don't know anything about using MATLAB code as a back engine for
your website.
