Detect moving object using blob

I have to detect object using "blob detection" but I don't know what is the function I need to use?

I used regionprops, also I tried to use boundary

my supervisor said to me "this is not blob detection" I feel confused, I have to submit this after two day ! Can anyone please help?

Sure. Read this link and come back with your image and description of what you want to measure in the image (like count, size, centroid location, intensity, or whatever).
