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?
