Problems solved by technology

[0005] The evaluation of picture quality is done manually, which is highly subjective and inefficient; pictures are stored by UI designers or project-related personnel, and the management is scattered, making it difficult to refer to and compare with each other

Abstract

The invention discloses a picture quality evaluation method and system, and relates to the technical field of computers. A specific embodiment of the method comprises: obtaining a target picture and aproject identifier of a visual specification project to which the target picture belongs, and extracting picture information of the target picture; according to the picture information, calculating ametric value of a set evaluation parameter of the target picture; obtaining a reference value of the evaluation parameter according to the project identifier, wherein the reference value is determined by calculating metric values of evaluation parameters of a plurality of reference pictures; and comparing the metric value of the target picture with the reference value according to a set comparison rule to obtain an evaluation result of the target picture. According to the embodiment, by extracting the picture information of the target picture, generating the digital evaluation parameter and then comparing the digital evaluation parameter with the reference value of the evaluation parameter, automatic evaluation of the picture quality is realized, the evaluation efficiency is improved, andthe evaluation result is objective and fair.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and system for evaluating picture quality. Background technique [0002] In the actual business of the Internet, a user interface (UI) designer is required to design a large number of pictures. In order to ensure the relative consistency of pictures designed by multiple UI designers, a series of visual specifications need to be set. For example, each part of the picture tends to be a whole, the core object tends to be in the center of the picture, the color change of the picture is not abrupt, and the picture is kept relatively neat, etc. [0003] In the prior art, the UI designer usually evaluates the image quality according to the visual specification, and after the image design is completed, the UI designer or project-related personnel perform storage and management. [0004] In the course of realizing the present invention, the inventor finds that there are at le...
