An automatic analysis method of human target parts based on multiple images

Abstract

The invention discloses a human body target part automatic analytic method based on multiple images, and belongs to the field of computer vision and image processing. According to the method, on the basis that the multiple human body target images are given, by means of concurrence among targets, human body target parts in the images are automatically analyzed. By means of the method, a human body target classifying module and a human body target analyzing module are executed in an iterated mode until the stopping condition is reached. The human body target classifying module achieves automatic classification of the multiple human body target images. In a classifying process, appearance similarity and gesture similarity among the human body targets are considered comprehensively; the human body target analyzing module achieves automatic analysis of the human body target parts in each classification and alignment of analyzed results of different classifications. According to the method, independent analysis of each human body target image is converted into simultaneous analysis of the multiple human body target images, and the limitation caused by a traditional analysis mode that learning is conducted and then inference is conducted is overcome.

Description

technical field [0001] The invention belongs to the field of computer vision and image processing. Specifically, the invention relates to a method for automatically realizing analysis of human body target parts in multiple images, and is a basic technology for applications such as human body target modeling. Background technique [0002] Object parsing in images is an important branch of computer vision and image understanding, and is often used to realize object recognition, segmentation and pose estimation in images. Traditional image object parsing techniques require two key steps. A critical step is the offline modeling process of target part annotation. Another critical step is the online inference process of target component parsing. In the offline process, the definition of the target part and the labeling of the target part need to be performed. The definition of target parts is to determine which basic elements a target consists of. Almost all previous works def...
