Help with cropping a binary image?

I have this binary image:

How do I crop exactly to the outline of the fist?

Answer 1

[Spandan Tiwari]

Use IMCOMPLEMENT to invert the polarity of the binary images so that the object (fist) is white. Then use BWBOUNDARIES to get the boundary pixels of the object.

[Shravanthi]

Thank you! But can you show me how bwboundaries works?

[Image Analyst]

boundaries = bwboundaries(~binaryImage);

but that gets you the outline coordinates of the fist. Is that what you want, or do you want the bounding box?

[Anjana Rao]

No, I just want the outline! How do I crop it after getting the coordinates? imcrop(?)?
