Hi, I have edge detected image. I want to connect all the pixels at extreme edges and fill the region inside, so that i have a binary mask of this image without any gaps. I used imdilate but this introduce thickness in boundries that i do not want in image. Can anyone please guide how I can do it. thanks

在 MATLAB Online 中打开

activecontour_demo.m

Try

mask = bwconvhull(mask, 'union');

or else try imclose() followed by imfill(), or try activecontour() (demo attached).

Thanks a lot, i used bwconvhull followed activecontour and with 200 iterations and got desired results. I was able to use activecontour as I have original image from which i created edge detected image initially.
