multiple contours from a given polygon

Dear All, I am trying to draw multiple contours on an irregular shape. So far I have done is that I got an initial boundary by using bwboundaries (file is attached). I would really appreciate, if somebody help me to draw multiple of these contours and return contour points. Contours should be separated by a fixed distance to the minimum possible level. best regards Mahboob Rehman
