Embodiment Construction

[0031] figure 1 It is the overall framework of the present invention, and is a schematic flow chart of each step method in the present invention. Such as figure 1 As shown, a shot retrieval method based on fuzzy cluster analysis, including the following steps:

[0032] 1. Shot segmentation

[0033] First, use the spatio-temporal slice algorithm (spatio-temporal slice) to segment the video database, and take the shot as the basic structural unit and retrieval unit of the video. For a detailed description of the spatio-temporal slice algorithm, please refer to the document "Video Partitioning by Temporal Slice Coherency"[ C.W.Ngo, T.C.Pong, and R.T.Chin, IEEE Transactions on Circuits and Systems for Video Technology, Vol.11, No.8, pp.941-953, August, 2001].

[0034]2. Establish fuzzy similarity matrix R

[0035] The method of establishing the fuzzy similarity matrix R between the internal images of the lens is as follows: when i=j, let r ij is 1, when i≠j, let r ij for x ...

Abstract

The present invention relates to a method of making video search of scene based on contents. It uses the fuzzy aggregation analysis method in the scene search. As compared with existent method it canobtain higher accuracy and quick searching speed.

Description

technical field [0001] The invention belongs to the technical field of video retrieval, and in particular relates to a content-based video retrieval method for shots. Background technique [0002] With major technological advances in the production, storage and dissemination of multimedia data, digital video has become an integral part of people's daily lives. The problem people face is no longer the lack of multimedia content, but how to find the information they need in the vast multimedia world. From the current point of view, the traditional video retrieval based on keyword description can no longer meet the needs of massive video retrieval due to limited description ability, strong subjectivity, manual annotation and other reasons. In order to make it easier for people to find multimedia data, content-based video analysis and retrieval technology has become a hot topic in research since the 1990s. The gradual formulation and improvement of the multimedia content descri...
