Does anyone have suggestions on how to say, create a circle and move it around in a rectangular image, where the circle is 1's and the background is 0s. Or to change the size of the circle, or make a triangle, etc.
I figure you use poly2mask and some graphics tools but I'm not exactly sure how

you can insert a shape in a image using the function 'insertShape'.
e.g.
RGB = insertShape(I,shape,position);
