A method and system for extracting video key frames

Abstract

The invention discloses a video keyframe extracting method and a video keyframe extracting system. The method comprises the following steps of reading video data which consists of a plurality of picture frames; extracting candidate keyframes from the video data to obtain a candidate keyframe set; classifying the candidate keyframes in the candidate keyframe set to obtain at least two clustering sets; and extracting the keyframe from the clustering sets. By the mode, the video keyframe extracting method and the video keyframe extracting system have global superiority, the computing speed is high, and actual application demands are met.

Description

technical field [0001] The present invention relates to the technical field of data processing, and in particular, to a method and system for extracting video key frames. Background technique [0002] Video refers to the technology of capturing, recording, processing, storing, transmitting and reproducing a series of static images in the form of electrical signals. The video data is composed of multiple picture frames, and the multiple picture frames are played in a preset order and at a preset speed to form a video. [0003] With the development of the Internet, video data has exploded, and how to quickly find interesting content from massive video data has become a challenge. like figure 1 As shown, key frames are usually included in the picture frames composing the video, and the key frames are image frames used to describe a shot, and usually one or several key frames can represent the main content of a shot. Retrieval through key frames can greatly reduce the amount ...
