AI Technical Summary

Problems solved by technology

Usually, because the initial search results are generally poor, labeling positive samples often requires in-depth browsing of the initial search list, which greatly increases the burden on users and hinders the promotion and use of this technology.
[0008] This greatly increases the user's search burden, and few users are willing to spend a lot of time for this

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030]According to the technical solution introduced above, the present invention can be easily applied to the existing video search system to provide users with personalized and accurate video search services. The present invention only focuses on the interactive search part, and assumes that the video has been cut into small video segments (lenses) one by one, and has used speech recognition and machine translation technology to convert the voice information corresponding to the lens into unified English text information, And an initial search result is given. In conjunction with the accompanying drawings, the specific embodiments of the present invention will be described in detail.

[0031] As shown in Figure 1, the overall system flow chart of the present invention includes the following parts:

[0032] 1. Multi-view feature extraction ...

Abstract

The invention discloses a multi-visual angle-based interactive video searching method, belonging to the field of video searching technique. And the invention applies multi-visual angle technique to interactive video searching. And the invention constructs a new arranging function from multiple independent visual angles in a semi-supervised learning mode and its advantage: it only needs very few label samples to be able to start a learning course and iteratively increases sample capacity from multiple visual angles and finally improves searching performance.

Description

technical field [0001] The invention relates to a multi-angle-based interactive video search method, which belongs to the technical field of video search. Background technique [0002] With the rapid popularity of video capture equipment (such as digital cameras, camcorders, etc.), and the rapid development of video production, storage, transmission and other technologies, video data is ubiquitous in our lives, and the amount of data is huge, even the DV of family selfies Also count G at every turn. Therefore, how to accurately search out the information needed by users from such huge video resources has become an urgent problem to be solved. Video search technology will be the core of the new generation of search engines, and also the key technology for establishing digital libraries, intelligent information query systems, and friendly human-computer interaction systems in the future. It has great potential in the fields of biomedicine, military affairs, education, enterta...
