Use bwlabel() and ismember
[labeledImage, numRegions] = bwlabel(binaryImage);
props = regionprops(labeledImage, 'Area')
% Compute all the areas.
allAreas = [props.Area]
% Display each blob in its own figure.
for k = 1 : numRegions
thisRegion = ismember(labeledImage, k);
figure;
imshow(thisRegion);
drawnow;
end
