Embodiment Construction

[0036] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0037] First, some technical concepts or technical terms involved in the present invention are explained.

[0038]The frame type defines a frame format, which specifically includes at least one of the following: an intra-coded frame (also called an I frame), an inter-frame predictively coded frame (P frame), and a bidirectional predictively coded frame (B frame).

[0039] A frame, which may also be referred to as an image frame, refers to an image frame (or video frame) transmitted by a video processing device. The present invention specifically divides frames into two types according to frame types, which are I frames and non-I frames, and the non-I frames may specifically be B frames or P frames. In practical applications, a frame is composed of several pixels, and each pixel has a definite position and an assigned color value (ie, pixel value). The position...

Abstract

The embodiment of the present invention discloses a video processing method, including: acquiring a video including M frames, M is a positive integer, each frame of the M frames includes at least one macroblock, and according to the macroblocks of the M frames The macroblock parameters of the M frames determine a set of candidate frames, the candidate frames in the set of candidate frames include a target area, and the target area is the area where the dynamic object in the video is located; if the candidate frame The set includes an intraframe coded I frame, and the I frame is selected as the target frame; if the candidate frame set does not include an I frame, the frame with the smallest frame number is selected as the target frame in the candidate frame set; for the target The frame is decoded to obtain the pixel information of the target frame; and the feature information of the dynamic object is extracted according to the pixel information. By adopting the embodiments of the present invention, problems such as heavy workload and slow processing efficiency existing in existing video processing schemes can be solved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a video processing method, related equipment and computer storage media. Background technique [0002] With people's increasing concern for social public safety and the wide application of urban surveillance networks, a large number of surveillance cameras are used in public places for video surveillance. Among them, in video surveillance, as users focus and pay attention to valuable information in video surveillance, image processing technologies such as face recognition and vehicle recognition have been born. [0003] At present, in order to realize the acquisition of value information, a video processing scheme based on feature extraction is proposed. Specifically, the video processing device decodes the video obtained by video surveillance into individual image frames (also called frames), and then performs pixel-level search and comparison on the frames to determine the i...
