Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] The schematic flow chart of the present invention is attached figure 1 As shown, after the face information is captured by video, face detection is performed, and then eye positioning, eyebrow positioning, lip positioning, facial contour extraction, and skin roughness calculation are performed according to the face detection data, and then the processed data is passed through The recognition classification and evaluation are compared with the standard portrait data to obtain the evaluation result of facial beauty.

[0037] Specifically include the following main technical points:

[0038] 1. Video capture

[0039] The first step in this invention is to build a real-time video capture system. In order to improve the speed of video collection and meet the real-time requirements, the present invention adopts DirectShow technology for video collection. The Micro...

Abstract

The invention provides a method for evaluating beautifulness of human faces based on video. The method is achieved by following steps: (1) capturing the face information by video; (2) effectively detecting the face according to the captured information by a cascade classifier based on haar-like characteristics; locating the eyes and the lips on the basis of the face detection, including detecting eyes by adopting a Sobel edge detection operator and a region growing method and determining the boundary of the lips according to the projection of red pixel dots in the face image; (4) extracting the face contour by adopting Snake model; and (5) comparing the extracted information with a face beautifulness standard library to determine the face beautifulness evaluation result. The method can achieve the real-time face beautifulness evaluation by capturing the face video information by a computer, and training to obtain the beautifulness classification standard according to a large amount of face samples.

Description

technical field [0001] The invention relates to computer image data processing and pattern recognition technology, in particular to a system for objectively evaluating the beauty degree of a human face by a computer. technical background [0002] Evaluating whether a person is beautiful or not is inevitably affected by the subjective factors of the evaluator, which is generally considered to be an abstract task. Different nations have their own evaluation standards. Taking women as an example, Europeans regard large mouths as beautiful, but Orientals think that small mouths are beautiful. And the same nation has very different aesthetic standards in different periods. People in the Han Dynasty liked to be thin like Zhao Feiyan, but in the Tang Dynasty they liked plump like Yang Yuhuan. Even in the same nation and in the same era, different individuals have different evaluations of beauty. Therefore, it is difficult to produce a unified standard for the evaluation of beauty....
