Abstract

The invention discloses an image definition judgment method, device and system. The method comprises following steps of calculating a first weight image of a to-be-judged image in a time domain; calculating a second weight image of the to-be-judged image in a frequency domain; and calculating the definition weight image of the to-be-judged image according to the first weight image and the second weight image, thus judging the definition of the to-be-judged image. According to the method, the device and the system provided by the invention, the definition of the image is described in combination of the time domain information and the frequency domain information of the image, thus judging the definition of the image; and further the quality of the image is evaluated.

Description

technical field [0001] The present disclosure relates to image processing technology, and in particular, to a method, device and system for judging image clarity. Background technique [0002] Image sharpness is one of the indicators used to measure image quality, which refers to the clarity of each texture and its boundary on the image. However, image sharpness evaluation is a relatively complicated problem, which is closely related to the content of the image. Therefore, judging the sharpness of the image is of great significance to the quality of the image. Contents of the invention [0003] In order to overcome the problems existing in related technologies, the present disclosure provides a method, device and system for judging image definition. [0004] According to the first aspect of the embodiments of the present disclosure, a method for judging image clarity is provided, including: [0005] Calculating the first weight map of the image to be determined in the ti...
