Hi Olivier...please tell me how to define V . what do u mean by integer unit8 ??

i appreciate if u can write down an example.
thanks

I hope the tool is useful

Seems to work well once tweaked. It won't run out-of-the-box, though.

1) Go to PolyMaskFilter.m and change if ~exist('basis') for if exist('basis') ~= 1. It's a matlab version issue.

2) After selecting the area to be cropped, you need to right click on the image and click crop. It's a little unintuitive.

3) You may need to hardcode or otherwise adapt parameter estimation, such as background std.

4) The 'manual threshold' option can only be use to give the low threshold.

After fixing these, it seems to give me a pretty good result, though I've yet to evaluate whether it will work on images universally.
Thanks for posting. Good luck to users.

Much faster than medfilt3.
