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

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

MATLAB: Regionprops

Try this for a start:

img = zeros(5,5);
img(2:4, 2:4) = 1;
props = regionprops(img, 'PixelList');
disp(img);
disp(props.PixelList);

You can change the pattern of ones in img until you're clear about how the result is structured. Another simple but informative example:

img = zeros(5,5);
img(2,2) = 1;
img(4,4) = 2;
props = regionprops(img, 'PixelList');
disp(props(1).PixelList);
disp(props(2).PixelList);
