Abstract

The invention discloses a face recognition method and a mobile terminal. The face recognition method comprises the following steps: obtaining image data of a video image output by a camera by a mobile terminal and extracting illumination data from the image data; confirming a coordinate position of a recognized face in the corresponding video image by using a face recognition algorithm according to the illumination data; confirming the display size and the display position of the recognized face on a screen of the mobile terminal according to the size of the corresponding video image of the recognized face, the size of the screen of the mobile terminal and the coordinate position of the recognized face in the corresponding video image; displaying the recognized face on the screen of the mobile terminal. The face recognition method and a face recognition system can realize the face reorganization by the mobile terminal at low cost.

Description

technical field [0001] The present invention relates to image processing, in particular to a mobile terminal and a method for face recognition based on video images using the mobile terminal. Background technique [0002] With the development of computer and image processing technology, face recognition technology has become relatively mature. According to the input video image, extract the brightness component data in the image data, calculate the face feature points (eyes, eyebrows, nose and mouth, etc.) according to the brightness data, and then match the corresponding feature point positions in the face model to identify human face. [0003] In the prior art, a special processing chip and a corresponding display device are generally used to realize face recognition. The input image is processed by the special processing chip, and then the recognized face is displayed through the corresponding display device. The cost of such a specialized processing chip is relatively...
