Problems solved by technology

[0003] For example, basketball is one of the most common sports in the world. There are many professional and non-professional games throughout the year. Attractive clips, such as brilliant attack and defense, eye-catching fouls and decisive timeouts, etc., so the content retrieval method of the full-court basketball game must become a compelling multimedia application; moreover, basketball or Similar sports events all have many of the same characteristics. For example, the stadium (competition scene) is a noisy environment, that is, when an exciting moment occurs, the live report of the live broadcaster is likely to be applauded by the audience. drowned out by sound

Embodiment Construction

[0014] The present invention is a screen content analysis, segment index and retrieval technology applied to motion films. It mainly uses the applause of the audience recorded in the motion film as the retrieval condition for dividing the motion film into several segments. Athletes tend to give applause for their outstanding performance, and the more outstanding the performance, the more intense the applause, so they are scored according to the intensity of the applause, and then these applause sections are extracted and sorted according to the scores of each section, so that the sports Movies provide an index of content sections with simple audio or even video features.

[0015] In the calculation flow chart in Figure 1, the sound characteristics used are based on the cheering properties in the time domain. Take the basketball game video as an example. In general, there are two announcers describing the situation in a basketball live broadcast program. Their The (sound wave) ...

Abstract

The invention applies recorded cheering voice in sports film as the retrieval condition to separate film into some segments as the better the player acts, the more the audiences cheer. It grades the cheering voice as its severe level, orders film segments according to segment's scores, and provides content segment retrieval with simple voice even video feature.

Description

technical field [0001] The present invention relates to a picture content analysis, segment index and retrieval technology of a movie, aiming at providing a content segment index with simple sound and image characteristics for moving movies. Background technique [0002] Content-based video indexing, retrieval and data processing are getting more and more attention nowadays, and the research results can be widely used in digital libraries, non-linear video indexing and video-on-demand services, especially in In the analysis of motion video, observation of motion video reveals that audio information is more efficient and clearer in detecting events than visual analysis. [0003] For example, basketball is one of the most common sports in the world. There are many professional and non-professional games throughout the year. Attractive clips, such as brilliant attack and defense, eye-catching fouls and decisive timeouts, etc., so the content retrieval method of the full-court ...
