Problems solved by technology

People are accustomed to using high-level semantic concepts to judge similarity, but most of the existing video content retrieval is at the non-semantic level
Due to the "Semantic Gap" between low-level features and high-level semantic concepts, it is currently not possible to achieve effective retrieval of video surveillance content on the network and in the video library at the same level.

Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0025] figure 1 For the video semantic gateway architecture provided by the embodiment of the present invention, the video semantic gateway includes:

[0026] The video semantic analysis unit establishes a semantic index pool, analyzes and understands the low-level information of video content, obtains three-layer semantic information of sensory semantics, structural semantics, and conceptual semantics, and conducts hierarchical research and improvement on these three-layer semantic information. The structure is based on The video retrieval model of these three layers of semantic information to establish an index of suitable videos or video clips and carry out semantic annotation;

[0027] The user request registration unit registers the content data...

Abstract

The invention provides a video semantic gateway. By analyzing and understanding the lower-layer information of video contents, the information of three layers of semantics, namely feeling semantics, structural semantics and conceptual semantics is acquired, researched in a layered mode and gradually perfected, and a video retrieval model based on the three layers of semantics is constructed and realized on a video gateway. With the video semantic gateway, content-based retrieval on a network and in a video library can be realized, and a retrieval interface based on content semantics is nor required to be provided by a resource provider. By the video semantic gateway, the reliability of video analysis and the speed and the efficiency of video retrieval can be improved.

Description

technical field [0001] The invention relates to the fields of video and security monitoring, in particular to video analysis, storage and retrieval. Background technique [0002] The main function of the video surveillance system is to monitor various live situations. It enables managers to observe the situation of all important places in the control room, such as installing cameras in important places such as entrances and exits, main passages, garages, etc., and transmitting the situation of the monitoring area to the management center in real time in the form of images. You can keep track of what's going on in these important places. [0003] Among them, the video surveillance system needs to meet the following requirements: the parts to be monitored include the equipment in the site, batteries, doors, access passages outside the site, etc.; The playback image is clear, and the monitored parts, especially the key parts, must be recorded 24 hours a day; the control syste...
