Using the interface provided by the OPENCV library, the face recognition function is realized. In a human face recognition system, it is very important to use a variety of preprocessing techniques to standardize the pictures to be recognized. Most face recognition algorithms are very sensitive to light conditions, so if they are trained in a dark room, they may not be recognized in a bright room. Such as the face should also be in a picture is a fixed position (such as eye position for the same pixel coordinates), fixed size, rotation angle, hair and decoration, expression (laughter, anger), light direction (left or upward), which is in face recognition, the use of good the image preprocessing filter very important reason. You should also do some other things, such as the removal of redundant pixels around the face (such as elliptical mask, showing only the face region rather than the internal hair or picture background, because they change more than the face area).
