Embodiment Construction

[0033] The technical solution of the present invention will be further described in conjunction with specific implementation below.

[0034] The implementation uses the actual photographs of faces taken as the training library to build the AAM model, which is the preparatory work before implementing the following technical solutions.

[0035] The specific implementation process of the technical solution is as follows:

[0036] 1) Initially locate the face in the input photo, mark the rectangular area containing the face, and discard other parts of the photo. In this step, use Adaboost to perform face detection on the input photo to find out the rectangular area where the face is located. This area is not close to the edge of the face, but it can be slightly larger than the face, but the face is guaranteed to be included in the area. Crop the photo to keep only the rectangular area, and the obtained photo will enter the subsequent processing. If there is a large non-face area...

Abstract

A method for automatically synthesizing multi-sheet of human face photograph includes positioning human face position in each inputted photograph preliminarily, accurately labeling outline and facial features by utilizing multiple constraint of positioned total or partial information of human face, carrying out color regulation automatically on each photograph to obtain unified color, utilizing deformation algorithm and interpolation synthesis of each pixel color to obtain a sheet of human face photograph with characters of each inputted photograph clearly and truly.

Description

technical field [0001] The invention relates to the technical fields of face detection, feature point tracking, multi-image synthesis and the like, in particular to an automatic synthesis method of a plurality of face photos. Background technique [0002] With the development of computer vision and the rapid improvement of hardware speed, some theories and methods of computer vision have reached the level of practical application under common hardware conditions. In recent years, some commercial software and services based on computer vision have gradually appeared and promoted to the public. The method of the present invention utilizes human face detection and feature point tracking, which are more researched in the field of computer vision, to realize the synthesis of multiple human face photos. [0003] Face detection and tracking of facial feature points is an unsolved problem in the field of computer vision, and it is also an important technology in applications such a...
