Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings. Such as image 3 As shown, the video program content is divided into marked shot paragraphs and unmarked shot paragraphs, and is distributed in each time segment of the whole video. The present invention analyzes each marked shot paragraph by analyzing the marked shot paragraphs. Summary of main characters. There have been many methods and inventions described on how to obtain the time position information of the marked lens segment, for example, extract the unique mark of the fixed position from the key frame, obtain positive and negative samples, and use the support vector machine (SVM) Train a template to determine whether it is a logo, use the template to extract key frames from the program video to be processed, and decide whether it is a key frame of a marked shot segment, so as to integrate the time information of these key frames to obtain a marked sho...

Abstract

The invention provides a method for automatically generating a main character abstract in a television program. According to the method, image characteristics and an unsupervised clustering method in a video are combined, so that main characters in a program video are extracted, an interviewer and an interviewee are marked, and a preview of the main character abstract is generated; and therefore, the user experience is enhanced. The method comprises the following steps of: extracting a key frame at a uniform time interval based on a video paragraph with marks, performing face detection and characteristic extraction, performing linear clustering on face images based on characteristics, obtaining rough character classifications according to time information and space information of the face images, obtaining a precise clustering result through graph-theory-based clustering, filtering the main character classifications of independent paragraphs by an adaptive method, integrating filter results of all the paragraphs, secondarily performing the graph-theory-based clustering, judging the interviewer and the interviewee according to a rule, and marking and generating the main character abstract of each paragraph. By the unsupervised clustering method, the structure is simple, and the method is easy to implement; and the method is relatively high in universality and robustness.

Description

technical field [0001] The invention belongs to the field of multimedia information processing and retrieval, and uses the extraction and analysis of the face features of characters in images in videos to provide a method for summarizing main characters in TV content. Applying the inventive method can automatically generate a summary of characters, and can mark interviewers and interviewees, and is a method for processing video content of TV programs with automatic calculation, strong robustness and low algorithm complexity. Background technique [0002] Nowadays, with the rapid spread and vigorous development of radio and television and the Internet, multimedia information as the data side has also been greatly increased. These massive data have spawned many emerging applications: digital TV, Internet TV, video websites, etc. , the needs of users for browsing experience and viewing experience have also increased accordingly, and it has become an urgent requirement to be abl...
