Embodiment Construction

[0016] figure 1 This is a flow chart of the creative method. The human body motion tracking method includes the steps: Step I: Provide a continuous multi-frame dynamic image, the dynamic image includes a background image segment, and a dynamic person as the foreground and the background Working image segment; the preferred background image segment is an image segment with only an independent stable background. This type of image segment facilitates accurate and rapid background creation. Of course, an image segment containing part of the moving foreground can also be used as the background image segment; Step II: Input each frame in the background image segment to perform background modeling processing to establish a background model; Step III: Perform image preprocessing on each frame of the working image segment; Step IV: Perform image preprocessing on each frame of the working image segment Human body position processing is performed on each frame of the frame to obtain and o...

Abstract

A tracking method of human body motions and an identification method thereof are disclosed. The tracking method includes the following steps: providing a continuous and multi-frame dynamic image and establish a background based on the dynamic image; simultaneously performing a pretreatment and a human body position process on every frame of the image so as to acquire and output human body position information of the frame. The identification method includes the following steps: arranging a human body identification mode, such as a mouse mapping mode, a state mode, a motion mode and the like; identifying the human body position information of the every frame based on the human body identification mode and outputting the identification information. By using the methods of the invention, a video can be tracked continuously, high-accurately and real-timely for the every frame and the human body position information can be output. Especially, the methods can be used to tracking the motions of small face sport organs, such as eyes, a mouth and face muscles and motions of an upper limb part with a large motion amplitude, a high frequency and complex motion characteristics. Simultaneously, attitude information, such as a mouse position, a mouse movement, single click, double click, hands position, a left hand movement from left to right and the like, can be identified and output.

Description

Technical field [0001] The invention belongs to the field of human motion tracking and recognition, in particular to a method for tracking and recognizing dynamic human faces and main motion joints of the upper body in an image. Background technique [0002] Human body motion tracking and recognition theory is currently a relatively advanced theoretical assumption, which involves computer software and hardware systems, automation and human science theories. The purpose of this system is to obtain the movement information of the human body by tracking and analyzing the movement parameters of the human body, and to analyze and recognize them. This topic is in Virtual Reality, Smart Surveillance Systems, Advanced User Interface, Motion Analysis, Recognition of Gesture, Content-based Video Classification ( Content-based Classification), Video Sequence Compression (Video Sequence Compression) and Computer Animation (Computer Animation) all have broad application prospects. There are...
