Device and method for automatically judging quality of digital picture

Abstract

The invention provides a device and a method for automatically judging the quality of a digital picture. The device for automatically judging the quality of the digital picture comprises a picture quality pre-detection unit, a picture size checking unit, a weight setting unit, a face identification checking unit, a picture quality judgment unit, a color cast checking unit and a picture output unit. The invention also discloses a method for automatically judging the quality of the digital picture. The method can be applied to digital media to serve as an evaluation basis for picture quality, and pictures which conform to the reception psychology of a majority of users are screened on the basis of the reception psychology of the majority of users. The method has a goal that the size and thecolor saturation of the screened picture are more suitable to be displayed on a digital media screen.

Description

technical field [0001] The invention belongs to image processing technology, in particular to a device and method for automatically judging the quality of digital pictures. Background technique [0002] Image quality evaluation technology plays a very important role in many image processing applications. Today's image quality evaluation methods can be divided into subjective evaluation and objective evaluation. Subjective evaluation is the ultimate standard of image quality, but subjective evaluation is very important for the actual image processing system. Saying is usually not realistic. In recent years, many researchers have invested in objective image quality evaluation methods. In the era of digital media, a picture that conforms to the acceptance psychology of most users plays a major role. The existing evaluation and screening are all artificial evaluations, which are highly subjective. Contents of the invention [0003] In view of this, the main purpose of the pre...
