We are doing a project on ear recognition. We have got the edges of the ear in a figure & have found the centroid of each. We have also drawn lines from the centroid at 10 degree intervals. Now we need to know how to find the points of intersection of these lines with our ear edges in matlab. Any help would be greatly appreciated.

There is great submission on MATLAB Central File Exchange to find curves intersections:
Fast and Robust Curve Intersections
If your ear edge represented as curve and you can calculate at least 2 points for each lines, you can find their intersections very fast with this function.

The best solutions are those someone else already implemented for you. +1 for finding it.

thanks a lot yuk....tried it out but didnt really know what inputs to give in the code. I think it requires 2 points to be knowm of each line which is possible for the straight lines we draw from the centroid but i dont think its possible to get two points on our ear edge as its an abstract figure. Plz help....Any other method also to get features of our ear images in matlab to use in our neural network will be really helpful too. Thanks
