Problems solved by technology

Since the similarity of similar frames is very high, the similarity of the extracted features is also high. Therefore, the amount of calculation for feature extraction for each frame is too large, and there is a lot of information redundancy.

Abstract

Embodiments of the invention disclose a video detection method and device, and aims at improving the video detection efficiency. The method comprises the following steps of: extracting a key frame feature map of a to-be-detected video; predicting a near frame feature map close to the key frame according to the key frame feature map; and carrying out corresponding detection on the to-be-detected video according to the key frame feature map and the near frame feature map. According to the method and device, the operand of video detection can be greatly decreased to improve the video detection efficiency, and information redundancy can be decreased.

Description

technical field [0001] The invention relates to the technical field of computer and image processing, in particular to a video detection method and device. Background technique [0002] The current video detection is mainly frame-based detection, and the detection network can usually be divided into two sub-networks: feature extraction network and object detection network. Among them, the feature extraction network extracts the features of each frame of the video, and the object detection network performs detection based on the features extracted by the feature extraction network. Since the similarity of similar frames is very high, the similarity of the extracted features is also high. Therefore, the calculation of feature extraction for each frame is too large, and there is a lot of information redundancy. Contents of the invention [0003] The purpose of the embodiment of the present application is to provide a video detection method and device, so as to improve the ef...
