Example Embodiment

[0042] In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes the application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, but not to limit the application.

[0043] It can be understood that the terms "first", "second", etc. used in this application can be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from another element. For example, without departing from the scope of this application, the first client may be referred to as the second client, and similarly, the second client may be referred to as the first client. Both the first client and the second client are clients, but they are not the same client.

Abstract

The invention relates to an image coding method and device, electronic equipment and a computer readable storage medium. The method comprises the steps of obtaining a main body area where a main body is located in a reference image; obtaining pixel blocks contained in the reference image, and carrying out coding processing on the pixel blocks by adopting a plurality of coding modes to obtain coding data corresponding to the pixel blocks in each coding mode; determining a target cost parameter of the pixel block based on the position relation between the pixel block and the main body area; obtaining the corresponding coding cost of the pixel block in each coding mode according to the target cost parameter of the pixel block and the corresponding coding data in each coding mode; and taking the coded data corresponding to the coding mode with the minimum coding cost as the target coded data corresponding to the pixel block. In this way, the distortion weight value or the code rate weight value of the pixel block can be dynamically adjusted, so that image details in or out of the main body area are reserved directly, and the image coding processing effect can be improved.

Description

technical field [0001] The present application relates to the field of image technology, and in particular to an image encoding method, device, electronic equipment and computer-readable storage medium. Background technique [0002] With the development of image technology, the application of video coding technology is more and more extensive. The current encoding technology mainly eliminates redundant information in data from three directions: spatial redundant information, temporal redundant information and statistical redundant information. For example, commonly used video compression standards H.264 / AVC and HEVC / H.265 generally adopt coding standards that generally use motion compensation, intra-frame prediction, and quantization coding frameworks that eliminate spatio-temporal redundancy. However, the traditional encoding technology still has the problem of poor encoding processing effect. Contents of the invention [0003] Embodiments of the present application pro...
