Abstract

The invention provides a picture compression quality factor obtaining method, system and device, and a storage medium. The method includes the following steps: obtaining a group of training pictures, and obtaining compression quality factors corresponding to the training pictures selected by users; calculating the number of color types and color difference numbers of multiple sampling points in the training pictures; constructing a two-dimensional coordinate system, and defining each training picture as one sample point in the two-dimensional coordinate system; defining a two-be-processed picture as a to-be-processed point in the two-dimensional coordinate system; and determining a compression quality factor of the to-be-processed picture on the basis of compression quality factors of one or more sample points that are closest to the to-be-processed point. The picture compression quality factor obtaining method, system and device are suitable for multiple application scenes, and a model establishing process is independent of parameters of a concrete picture compression algorithm so that a model can be suitable for multiple different picture formats. A quality evaluation module can continuously collect user evaluation data, the model is updated periodically, and changes of demands of the users are reflected in time.

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...
