Embodiment Construction

[0029] The following is a detailed description of the embodiments of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following Example.

[0030] Such as figure 1 and figure 2 As shown, this embodiment includes the following steps:

[0031] The first step is to use the frame difference method to process the periodic motion video captured by the still camera, and to obtain the difference image I diff Perform thresholding to obtain the moving edge I of the object silh .

[0032] I diff =I cur -I pre

[0033] I silh = I diff I diff ...

Abstract

The invention discloses a periodic motion detection method based on a motion video. The method comprises the following steps of: analyzing moving objects in the periodic motion video to obtain a motion vector table of a moving part; matching motion mode regions extracted from the video to implement optimum matching, thereby determining a motion mode in each frame; after matching the motion modes,classifying motion scenes to respectively filter non-periodic motions and retain the periodic motion through a method based on tracks and a method based on regions; and finally, judging eligibility of the periodic motion to count the number of motions. The method provided by the invention is featured by real-time property, has an identification efficiency of 95% for different motion situations, and has better application performance.

Description

technical field [0001] The invention relates to a motion video processing method, in particular to a motion video-based periodic motion detection method. Background technique [0002] Motion video analysis has important applications in fields such as video retrieval, sports training, and video editing. Video-based motion capture does not require direct contact with the monitored person during video surveillance, and is easily accepted by the monitored person, and has a wide range of applications. [0003] After searching the literature of the prior art, it is found that many different motion video analysis algorithms have been proposed. A.Ekin, A.Tekalp, and R.Mehrotra in "IEEE Trans. Circuits and Systems for Video Technology, vol.12, no.7, 2003." Issue No. 7, March 12) In the paper "Automatic Soccer Video Analysis and Summarization" published on pages 796 to 807, a framework for automatic analysis and summarization of football videos based on target features is proposed ...
