Labelise your image, then extract each unique label:

sourceimage = imread('index.png');
labelimage = bwlabel(sourceimage);
numobjects = max(labelimage(:));  %in R2018b: numobjects = max(labelimage, [], 'all');
objectimages = cell(1, numobjects);
for label = 1:numobjects
    objectimages{label} = labelimage == label;
    figure; imshow(objectimages{label});  %optional display
end

it works fine on some images but failed on the images like this.

If you're trying to isolate the black blobs instead of the white blobs as in your original then you'll have to invert the imge. bwlabel only detects white blobs. Black is always considered background.
