I have designed a edge detection method using morphological operations.
显示 更早的评论
How can I compare this method with existing methods like sobel, prewitt and canny? Are there any parameters to say that this method is superior or inferior

You mean you designed imtophat() or imbothat()?

You compare the performance of the algorithm to Ground Truth and come up with some kind of score.

Note that when you calculate the score for an actual edge determination that you would probably want to take into account the distance between the actual edge and the calculated edge, which is relatively simple if all of the edges are found, but gets more complicated if the calculated edges are missing some of the true edges (what penalty do you use?)

do you have code to .. extract morphological features of galaxy image like (i) area, (ii) centroid, (iii) bounding box, (iv) major axis, (v) minor axis, (vi) eccentricity, (vii) orientation, (viii) convex area, and (ix) extrema?
