I tried doing a pixel wise hole filling operation that is if its surrounded by pixels whose sum exceeds a certain number, fill it. However, this seems to thicken edges as expected. Is there any way I can fill these small holes in the image without changing edge dimensions?
Thanks

No idea what you're talking about. Where is the demonstration of this?

k=[1 1 1; 1 0 1; 1 1 1];
mask=conv2(YourImage,k,'same')>threshold;
YourImage=regionfill(YourImage,mask);
