I have two questions about snake edge detection. The first question is, in openCV there is a function cvSnakeImage(src,points,.......), what does the points parameter mean?

The second questions is: I want to apply this function on the part surrounded by an edge that I have already made, how can I do this?

This is my code for edge detection:

cvCanny(img_bw, img_canny , thresh, thresh * 50, 3);

cvFindContours(img_canny, contour, &contours, sizeof(CvContour), CV_RETR_TREE,    CV_CHAIN_APPROX_SIMPLE);

    Are you sure that function still supported by ocv? this is a [similar](http://stackoverflow.com/questions/15432797/cvsnakeimage-opencv-api-example-documentation) question – Hadi Apr 24 '14 at 05:13
  • cvSnakeImage was moved to legacy. and you should no more use the arcane c-api. please , buckle up! – berak Apr 24 '14 at 07:03
  • yes , it is supported . [link](https://fossies.org/dox/opencv-2.4.8/snakes_8cpp.html) – user3504947 Apr 24 '14 at 10:49

points parameter is the pointer to the snakes point array

Here is an example of how to use snakes
