opening by reconstruction results

I know the algorithm how it works. For illustration process i want to visualise output of opening by reconstruction in each iteration. in matlab the function just gives the final result obtained after stability is reached.

looking at the fucntion itself with edit imreconstruct, it calls a mex function for processing and there is no way to get individual output from imreconstruct.

No. You'd have to write that code yourself.

thats what i thought. thanks for the conformation.

Image analyst, could you give some hint what the process should be in terms of pseudo code that will help me to write full code?

[Image Analyst]

I'd start by searching the internet for a full description or pseudocode for doing morphological reconstruction.
