Have you run my Image Segmentation Tutorial http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862? It goes over that.
labeledImage = bwlabel(binaryImage);
blobMeasurements = regionprops(labeledImage, 'BoundingBox');
% Find the bounding box of each blob.
thisBlobsBoundingBox = blobMeasurements.BoundingBox; % Get list of pixels in current blob.
% Extract out this blob into it's own image.
% I'm assuming just one blob. If you have multiple, see my tutorial.
subImage = imcrop(binaryImage, thisBlobsBoundingBox);

You should have had this done long long ago - it's not that hard. So I did it for you. See the attached demo.
