Abstract

An embodiment of the invention discloses a video class identification method and device, a data processing device and an electronic device. The method comprises the following steps: carrying out subsection on a video to obtain a plurality of segmented videos; carrying out sampling on each segmented video in the plurality of segmented videos to obtain an original image and an optical flow image of each segmented video; processing the original image of each segmented video by utilizing an airspace convolution neural network to obtain an airspace classification result of the video; processing the optical flow image of each segmented video by utilizing a time domain convolution neural network to obtain a time domain classification result of the video; and carrying out fusion processing on the airspace classification result and the time domain classification result to obtain a classification result of the video. The video class identification method and device can improve video class identification accuracy.

Description

technical field [0001] The invention belongs to the technical field of computer vision, and in particular relates to a video category recognition method and device, a data processing device and electronic equipment. Background technique [0002] Action recognition is a popular direction of computer vision research. Action recognition technology mainly recognizes the actions in the video by processing the video composed of color picture sequences. The difficulty of action recognition technology lies in: how to process the dynamically changing video content to overcome changes in distance, perspective, camera movement, and scene changes to correctly identify actions in the video. [0003] At present, the commonly used action recognition technology mainly uses hand-designed feature descriptors to cooperate with classifiers such as support vector machines for action recognition. Among them, the most representative method is to use the improved dense trajectory descriptor as a ...
