I am working on Face detection using Core Image. I m facing a problem when giving the points on face boundaries. Actually I ve to give the points on face boundaries and make those points in a movable state.
Please share your ideas with me.. Thanks in Advance...
I will suggest you four ways. I have not done them in IOS. I implemented them in java. For face boundary detection you can use following methods:
If there are shadows in the face use Snake algorithm. If the faces in the images are clear then go for Skin Color Thresholding. Canny Edge Detection can give u very slow performance.
