Abstract

The invention provides an image compression degree identification method, which comprises the following steps: acquiring a target image, and identifying a target object edge region of the target image; carrying out segmentation operation on the target image by using a preset size to obtain a target image block related to the edge area of the target object; inputting the pixel gray scale value of the target image block into a preset neural network model to calculate the definition corresponding to the target image block; and calculating the definition of the target image according to the definition corresponding to the target image block, thereby obtaining the compression degree of the target image. The invention further provides an image compression degree recognition device, the compression degree of the target image is obtained based on the target image block related to the edge area of the target object, the recognition error and the recognition cost of video definition are reduced,and the recognition efficiency of video definition recognition is improved.

Description

technical field [0001] The present invention relates to the field of image recognition, in particular to an image compression degree recognition method, device, equipment and computer-readable storage medium. Background technique [0002] In online social media, images and videos usually go through multiple rounds of compression during the process of acquisition, upload, processing, storage and transmission. Although the compression algorithm represented by JPEG (Joint Photographic Experts Group) makes the above process more efficient, it inevitably reduces the display quality of images and videos, thereby reducing user experience. [0003] Sometimes when users create a video with various special effects, they usually use multiple software to process the video, which results in the video being uploaded and processed multiple times. During this process, the video is compressed multiple times, resulting in many JPEG compression traces, such as jagged edges on the edges of ima...
