Embodiment Construction

[0046] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] As described in the prior art, the current event identification involved in intelligent video analysis, such as: identifying potential or ongoing illegal and criminal events, and reviewing the video as required. The existing recognition models are lacking in recognition accuracy and recognition speed, and the recognition results are not ideal. see figure 1 , figure 1 It is a schematic flowchart of a method for identifying event...

Abstract

The invention discloses a method and system for identifying an event in a video. The method comprises the following steps: acquiring static characteristics of each frame in a video based on a neural network; acquiring spatial interaction relationship features corresponding to the static features based on a spatial attention mechanism network; obtaining space-time interaction relationship features corresponding to the space interaction relationship feature set based on a time domain attention mechanism network; constructing a space-time interaction relation graph based on the space-time interaction relation features, and obtaining features of the space-time interaction relation graph through a graph convolutional neural network; and identifying events in the video based on the space-time interaction relationship characteristics and the characteristics of the space-time interaction relationship graph. According to the scheme of the invention, the accuracy and efficiency of identifying the event in the video are improved.

Description

technical field [0001] The present invention relates to the technical field of computer vision, in particular to a method and system for identifying events in video, computer equipment, and a computer-readable storage medium. Background technique [0002] With the rapid development of computers, image acquisition equipment, and wireless transmission technology, video has become the most contacted form of streaming media in daily life. Video surveillance is a comprehensive system with strong prevention capabilities and an important part of the security system. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. For example, surveillance cameras in cities can capture surveillance videos of different scenes. However, although surveillance cameras can capture a large amount of surveillance video, they do not have the corresponding supervision and review capabilities, and in many cases, manual screenin...
