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 present disclosure relates to a method, a device, an electronic device, and a computer-readable storage medium for obtaining classifications of image blurring degrees. A method for obtaining an image blur degree classification includes: obtaining a fuzziness map and a saliency map of an image to be recognized; and determining the classification to which the blur degree of the image to be recognized belongs based on the fuzziness map and the saliency map. In this embodiment, by obtaining the fuzziness map and the saliency map, that is, the features of different dimensions comprehensively consider the classification to which the blur degree of the image to be recognized belongs, so as to avoid the misjudgment caused when the image block is used for local evaluation, for example, the background Determining a blurred image as a bad image helps to improve the accuracy of determining the degree of image blur, so that users can better manage images according to the degree of blur and improve user experience.

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...
