Embodiment Construction

[0014] The present invention relies on the following two assumptions for the extraction of sports game video highlights: (1) the highlight event will be replayed in time; (2) the first shot of the replay usually comes from the same camera that previously shot the event. on the basis of, figure 1 A schematic flow chart of the present invention is given. Firstly, the color histogram-based shot boundary detection and camera motion analysis are carried out on the video sequence, and the preliminary shot boundary is verified by the results of the camera motion analysis to eliminate the errors caused by motion. Then, it is judged whether or not the detected shot is to be replayed. If it is a playback shot, it will be judged as a highlight segment. On the other hand, according to the camera movement, the most similar shot to the first replayed shot is searched in the previous video clips, which is also determined as a highlight clip.

[0015] Camera movement includes the following...

Abstract

A method for detecting highlights in a sports game video, comprising the steps of: determining the camera motion of adjacent frames in the video; using the camera motion to correct the detection of shot boundaries; determining according to the presence or absence of replay signs in the image Whether the shot is a replay shot, if it is a replay, it is judged as a highlight; according to the camera movement, the similarity between the replay shot and the normal shot in the previous video is calculated, and the shot with the greatest similarity is judged to be a highlight . The invention can effectively and automatically extract highlights without relying on domain knowledge of specific games. For the large amount of motion in sports video, the present invention uses the result of camera motion analysis to verify the detected shot boundary, thereby improving the accuracy of shot segmentation.

Description

technical field [0001] The present invention relates to a method for detecting highlights in a video of a sports game. Background technique [0002] The TV broadcast of sports games is generally very long, but for the audience, it is only the highlights that really care about and may watch repeatedly. These highlights are not only of interest to ordinary audiences, but also to sports professionals, such as coaches who need to perform technical analysis on athletes' movements. The traditional method is to manually edit the recorded video tapes, but this method is time-consuming, laborious and requires professional skills. [0003] With the continuous development and popularization of digital technology, videos can be stored and processed in digital form. On this basis, some automatic processing of video image data can be carried out by computer. Some published methods exploit the domain knowledge of specific game scenarios to analyze videos of games such as football and ba...
