Abstract

The present invention provides a picture compression quality factor acquisition method, system, device and storage medium. The method includes acquiring a group of training pictures, and acquiring the compression quality factor corresponding to each training picture selected by the user; The number of color types and the number of color differences of a sampling point; construct a two-dimensional coordinate system, define each training picture as a sample point in the two-dimensional coordinate system; define the picture to be processed as a pending processing in the two-dimensional coordinate system point; determine the compression quality factor of the picture to be processed according to the compression quality factor of one or more sample points closest to the point to be processed. The present invention is applicable to a variety of application scenarios, and the establishment process of the model has nothing to do with specific image compression algorithm parameters, making it applicable to multiple different image formats; the quality evaluation module can continuously collect user evaluation data, and regularly evaluate the model Update to reflect changes in user needs in a timely manner.

Description

technical field [0001] The present invention relates to the technical field of picture processing, in particular to a method, system, device and storage medium for acquiring picture compression quality factors. Background technique [0002] With the popularization of the Internet and the development of Internet technology, various new business forms such as Internet + tourism have profoundly changed people's lifestyles. Pictures are an important medium for communication between sites and users, and their quality and response speed directly affect the user experience. In order to allow users to obtain image content faster and more stably, on the one hand, major websites generally use CDN (Content Delivery Network, content distribution network) acceleration technology, and its basic method is to form a virtual network by placing node servers around the network , and then intelligently route the user to the nearest node to download the picture. On the other hand, due to the l...
