Problems solved by technology

However, as the resolution of video images develops toward ultra-high-definition, more and more transmission resources are required for surveillance video, and the pressure on transmission bandwidth is also increasing. Therefore, it is necessary to improve the quality of encoding control , to reduce the pressure on the transmission bandwidth, that is, to compress the video stream without affecting the subjective quality, thereby reducing the amount of video stream data

Embodiment Construction

[0019] The solutions of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0020] In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application.

[0021] The terms "system" and "network" are often used interchangeably herein. The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship. In addition, "many" herein means two or more than two.

Abstract

The invention discloses a coding control method and a related device. The coding control method comprises the steps of obtaining a reference area associated with a target object in a to-be-tracked image; obtaining a feature value of at least one image feature of the to-be-tracked image and a feature weight corresponding to the image feature based on the image data of the reference area; determining a target position corresponding to each image feature in the to-be-tracked image based on the feature value of each image feature; performing weighting processing on the target position corresponding to each image feature by using the feature weight corresponding to each image feature to obtain a target area in the to-be-tracked image; and adjusting the quantization parameter of the to-be-tracked image by using the target area in the to-be-tracked image, and encoding the to-be-tracked image by using the adjusted quantization parameter. According to the scheme, the coding control quality canbe improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an encoding control method and a related device. Background technique [0002] At present, more and more camera devices such as surveillance cameras are deployed in densely populated areas such as stations, airports, commercial streets, squares, etc. The monitoring range of the monitoring system has been expanded, and the monitoring details that the monitoring personnel can obtain are becoming more and more abundant. However, as the resolution of video images develops toward ultra-high-definition, more and more transmission resources are required for surveillance video, and the pressure on transmission bandwidth is also increasing. Therefore, it is necessary to improve the quality of encoding control , to reduce the pressure on the transmission bandwidth, that is, to compress the video stream without affecting the subjective quality, thereby reducing the amount...
