Yes, it's Jacob (this photo) and I want to add more people like Aaron Swartz and other people related but now I'm just trying to find the contour of this image and then add more to the animation.
I really have no clue on image processing so I don't know what threshold, erode or dilate can do to an image. As you said, I probably have to process it in order to make the contours more visible for the function although I don't know where to start.
