Embodiment Construction

[0065] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with aspects of the present disclosure as recited in the appended claims.

[0066] When actually shooting images, many users will adopt the shooting method of blurring the background to artificially blur the background area of ​​the target subject to obtain an image with a clear target subject and a blurred background. If the method of image blocks in the related art is used to determine whether the image is blurred, it is impossible to distinguish whether the background is b...

Abstract

The invention discloses a method and device for obtaining image blurring level classification, electronic equipment and computer readable storage medium. The method for obtaining the image blurring level classification comprises the steps that blurring level graphs and significance graphs of images to be recognized are obtained; and classifications of blurring levels of the images to be recognizedare determined based on the blurring level graphs and the significance graphs. By obtaining the blurring level graphs and the significance graphs, that is, the features of different dimensions comprehensively consider the classifications of the blurring levels of the images to be recognized, the situation that misjudgment is caused, such as images with blurring backgrounds are intended to be badimages, caused by local evolution of image blocks is avoided, the accuracy rating of ensuring the image blurring levels is improved so that managing images better according to the blurring levels is convenient for users, and use experience is improved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to a method, device, electronic device, and computer-readable storage medium for obtaining image blur degree classification. Background technique [0002] In image processing fields such as image compression, video codec, and video surveillance, it is necessary to evaluate image quality to ensure reliable images in subsequent processes. Among them, the degree of image blurring is an aspect of image quality evaluation. [0003] In the related art, most evaluation methods of image blur degree are based on image blocks to determine whether the image is blurred, and then comprehensively judge whether the image is blurred according to the number of blurred image blocks and the blurring degree of each image. [0004] However, in actual shooting, in order to highlight the target subject, many users will use the background blurring method to artificially blur the bac...
