Thank you so much for quick and positive reply ...

I have tried this code but it only marked the boundaries of bw image ,,, but i want to connect the distinct pixel to form a connected smooth shape of Lung ... i have tried bwconnected pixel already ...

I hope you can help me ..

Let's see your code. activecontour() returns a binary image, not boundaries. What did you do with the bw variable that activecontour() gave you? That should be a smoother blobs image.

Dear ImageAnalyst

i got bw with another technique(Guassian gradient etc) ... i got the image names as ('im.png') .. but it gave me non linked edges of binary image ...

Thats why i asked for the help to connect distict edges ...
