The function call is RGB = insertObjectAnnotation(I,shape,position,label).

Change shape from 'rectangle' to 'circle', and change position from a bounding box [x,y,w,h] to a circle vector [x,y,r], where (x,y) are the coordinates of the circle center, and r is the radius.

All of this information can be found in the help documentation:
