Embodiment Construction

[0040] Hereinafter, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.

[0041] First, the terms / nouns involved in the embodiments of the present application are explained.

[0042] (1) Image encoding / decoding

[0043] Image coding is the process of compressing image sequences into code streams.

[0044] Image decoding is the process of restoring the code stream into a reconstructed image according to specific grammatical rules and processing methods.

[0045] At present, the encoding process of video images is as follows: the encoder first divides a frame of original image into multiple parts that do not...

Abstract

The invention discloses a moving object detection method and device and a storage medium, relates to the field of image processing, and can reduce the resource consumption of moving object detection, so that the moving object detection is suitable for most image processing equipment. According to the specific scheme, the method includes enabling a detection device of the moving object to obtain a code stream; determining a target object in the to-be-detected image frame according to a preset target detection algorithm, wherein the to-be-detected image frame is any one image frame in the code stream; determining a moving image block in a target area in the to-be-detected image frame according to the code stream, wherein the motion vector of the moving image block is greater than a first preset threshold, the target area is a preset area, the target object is an object in the preset area, or the target area is an area where the target object is located; determining the proportion of the target image block in the area where the target object is located, wherein the target image block is a moving image block located in the area where the target object is located; and finally, determining whether the target object is a moving object according to the proportion.

Description

technical field [0001] The present application relates to the field of image processing, and in particular to a method, device and storage medium for detecting a moving object. Background technique [0002] At present, image processing equipment usually uses object tracking algorithms in deep learning to detect moving objects in videos, such as moving people and cars. The use of target tracking algorithms for moving object detection consumes more resources of image processing equipment, and thus has higher requirements for the central processing unit (central processing unit, CPU), computing power and memory of image processing equipment, and the applicability is relatively high. Low. Contents of the invention [0003] The present application provides a moving object detection method, device and storage medium, which can reduce the resource consumption of moving object detection, so that the moving object detection is applicable to most image processing devices. [0004]...
