Embodiment Construction

[0013] figure 1 It is a flow chart of the creation method, and the human body motion tracking method includes the steps: Step I: Provide continuous multi-frame dynamic images, the dynamic images include background image segments, and have dynamic people as the foreground and the background Working image segment; the preferred background image segment is an image segment with only an independent and stable background, this type of image segment is convenient for setting up the background accurately and quickly, and of course an image segment comprising 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 the working image segment Human body position processing is performed on each frame to obtain and ...

Abstract

A method for tracking human body motions and a system thereof are disclosed. The method includes the following steps: providing a continuous and multi-frame dynamic image, wherein the dynamic image comprise a background image segment and a work image segment possessing dynamic people as a foreground and the background; inputting every frame of the background image segment and performing a background process so as to establish the background; performing an image pretreatment on the every frame of the work image segment; performing a human body position process on the every frame of the work image segment so as to acquire and output human body position information of the frame. By using the method and the system 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 method and the system 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, high frequency and complex motion characteristics.

Description

technical field [0001] The invention belongs to the field of human body motion tracking, in particular to a method and a system for tracking the main motion joints of the dynamic human face and upper body in images and outputting their position information. Background technique [0002] The theory of human motion tracking is a relatively advanced theoretical assumption at present, which involves computer software and hardware systems, automation and human body science theories. The system can track and analyze the motion parameters of the human body, obtain the motion information of the human body, and analyze and identify them. This subject has been studied 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) have broad application prospects. Good...
