MATLAB: How can i separate all the connected regions in a binary image and display them individually.

Question

I have small white pixel areas in my binary image, how can I extract only those white connected pixel areas and display them individually.

Answer 1

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
