Human body assembly dividing method based on face detection and key point positioning

Abstract

The invention provides a human body assembly dividing method based on face detection and key point positioning; the method mainly aims to an image with no overlap limb for dividing human body assemblies; the method comprises the following steps: inputting a human body image; using face detection technology to position a human body substantially scope; using edge detection to obtain an accurate human body layout; using a cross list storage and retrieval method to complete automatic dividing of the human body assemblies through key point search. The method uses the maturation face detection algorithm to complete face identification, and substantially positions the human body position according to face information and extracts the accurate human body layout, and searches and positions key points on the human body layout according to human body proportion constraint, and finally fast divides layouts of each human body assembly according to the key points. The method is high in instantaneity and accuracy, can be applied to human body three dimensional reconstruction, human body measurement, and behavior identification fields.

Description

technical field [0001] The invention belongs to the technical field of computer image processing, and in particular relates to a human body component division method based on face detection and key point positioning. Background technique [0002] The component division of the human body in videos or pictures can serve research and practical applications in many related fields such as accurate 3D reconstruction of the human body, measurement of human body components, and behavior recognition.
