Embodiment Construction

[0069] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0070] According to an embodiment of the present invention, such as Figure 1-Figure 5 As shown, a method for extracting behavioral features of multiple players in football game videos is provided.

[0071] Clothing Color Feature Extraction of Players and Referees

[0072] The technical scheme of the present invention uses the color classification learning set to find interesting regions by mapping image pixels to their respective color classes, and then uses morphological operators to group pixels. Using the mixed color space to detect the space yields the best distinction between pixels belonging to the opposing team and the referee.

Abstract

The invention discloses a method for extracting behavior characteristics of multiple athletes in football match video, which comprises the steps of a, color classification, segmentation and feature extraction; and b, robust processing of color classification. The method for extracting the behavior characteristics of the multiple athletes in the football match video can overcome defects of complex operation process, long time, low reliability and the like in the prior art, thereby realizing the advantages of simple operation process, short time and high reliability.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a method for extracting behavioral features of multiple players in football match videos. Background technique [0002] Since the football game is a kind of spectator sport, the venue, field lines, referees and players' clothing are designed to have unique visual effects. From a visual identity point of view, these color differences are one of the best messages: the field is green; the field lines are white; referees and players must be dressed to achieve the highest possible contrast. Color features can be used not only to improve tracking, but also to distinguish players belonging to different teams. Therefore, the color features of video images can be extracted for behavior recognition. [0003] In the process of realizing the present invention, the inventors found that the prior art at least has defects such as complicated operation process, long time-consu...
