Abstract

The invention provides an image quality evaluation method and device. The method comprises the steps: carrying out the target detection of a to-be-estimated image, so as to determine at least one target region; carrying out the quality evaluation of at least one target region, so as to determine the quality evaluation result of each of the target regions; and carrying out the quality evaluation of the to-be-estimated image based on the determined quality evaluation result of each of the target regions. The method provided by the invention enables an image quality evaluation process to focus on an AOI, and neglects the image quality of an inessential region, thereby achieving the quality evaluation of the to-be-estimated image. The method is high in evaluation speed, is higher in evaluation precision, and achieves the objective and effective evaluation of the quality of the to-be-estimated image.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to an image quality evaluation method and device. Background technique [0002] With the popularity of digital devices such as digital cameras, surveillance cameras, and mobile phones, digital images are more and more widely used. In practical applications, such as: face recognition, OCR, image classification, intelligent monitoring, etc., there are also certain requirements for image quality. How to effectively evaluate the quality of an image has become more and more important. The current image quality assessment methods, no matter with or without reference, are basically based on processing the entire image to obtain its corresponding quality index. In fact, when a computer performs quality assessment in this way, it does not really reflect the processing of human vision. The human vision system will automatically focus when evaluating the surrounding scene. T...
