Title:
IMAGE QUALITY EVALUATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/135391
Kind Code:
A1
Abstract:
An image quality evaluation method and apparatus. The method comprises: first obtaining a sample image, and then adjusting a brightness component of the sample image according to a shape parameter and different distortion levels to obtain a first training image set (S101); processing a first training image according to a preset image processor to obtain a second training image set (S102); performing image processing on the sample image according to a preset distortion type and different distortion levels to obtain a composite distortion training image set (S103); constructing an image quality evaluation model by taking the training image set, the distortion levels of images in the training image set, and a standard quality evaluation score of the sample image as inputs (S104); and obtaining an image to be evaluated, and inputting the image to be evaluated into an image quality evaluation model to generate a prediction quality evaluation score of the image to be evaluated (S105). By implementing this method, quality score evaluation can be performed on an image distorted by a single distortion factor, and quality score evaluation can also be performed on an image distorted by fusion of multiple distortion factors.
