Abstract

The invention discloses a method and device for detecting video scores. The method comprises the following steps of: combining a static area and an area with abundant textures in a video picture to obtain candidate score display areas; screening the candidate score display areas based on first filter conditions to acquire a score display area in the video picture; decomposing score display images in the score display area to acquire text areas in the score display images; and screening and matching the text areas based on second filter conditions to acquire score areas of the score display areas. According to the invention, video editing personnel can catalogue football videos quickly, thus work load of video editing personnel can be greatly reduced.

Description

technical field [0001] The present invention relates to the video field, in particular to a method and device for detecting video scores. Background technique [0002] For broadcast sports video, the change of score is very important, it provides very helpful information for video editing and analysis. For most sports videos, there will be a score board, which records the score that changes at any time. Obtaining the score information can help us mark and catalog the video. For example, for a football video, after getting the score information, you can mark the time point of the goal in the video, and further help to mark the highlights of the goal. These catalog information are very important for this video. [0003] The score detection method of related prior art is to detect score by the traditional method of character detection, mainly uses image processing technology to detect the text in each frame image, then uses video OCR technology to recognize text, this method i...
