--- Comment #16 from Chandra Kant <chandra.kant.ee...@itbhu.ac.in> --- I think for this issue -the more aligned faces are the better face recognition results are.So we need to convert the image to greyscale.Then we can rotate face to vertical position so it is aligned perfectly. we can do this by computing height difference between the eyes and when eyes are shut we can use histogram of oriented gradients for nose to get its orientation. First thing first we need to find eyes on picture. we can crop the image to just the face part so the classifier has easier job finding eyes and doesn’t throw false positives. -- You are receiving this mail because: You are watching all bug changes.
