Problems solved by technology

[0002] With the popularization of terminal devices such as smartphones, people are accustomed to taking pictures through terminal devices to record the details of life, and the pictures taken by some users may be blurred, resulting in low-quality pictures. Therefore, in order to save the cost of terminal devices Memory, it is necessary to detect low-quality pictures for related processing, such as deletion, etc.

Abstract

The disclosure, which belongs to the technical field of image processing, relates to an image quality analysis method and apparatus. The method comprises: gradient extraction is carried out on a to-be-processed image to obtain a gradient image and the gradient image is inputted into a preset convolutional neural network; an edge feature of the gradient image is processed according to a plurality of pre-trained convolution kernels in the preset convolutional neural network; and on the basis of a matching degree between the edge feature of the gradient image and a preset image edge feature, an image quality of a to-be-processed picture is determined. With the method, the image quality of the to-be-processed image is analyzed by using the convolutional neural network, thereby improving the accuracy and efficiency for determining the image quality of the to-be-processed image.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, in particular to an image quality analysis method and device. Background technique [0002] With the popularization of terminal devices such as smartphones, people are accustomed to taking pictures through terminal devices to record the details of life, and the pictures taken by some users may be blurred, resulting in low-quality pictures. Therefore, in order to save the cost of terminal devices Memory, it is necessary to detect low-quality pictures for related processing, such as deletion. Contents of the invention [0003] In order to overcome the problems existing in related technologies, embodiments of the present disclosure provide an image quality analysis method and device. Described technical scheme is as follows: [0004] According to a first aspect of an embodiment of the present disclosure, an image quality analysis method is provided, the method comprising: [0...
