I have this binary image:
How do I crop exactly to the outline of the fist?

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.

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?
