A method and device for recognizing blurred pictures

Abstract

The invention discloses a blurred picture identifying method and apparatus. The blurred picture identifying method comprises the following steps of acquiring a target picture; acquiring a gray scale picture corresponding to the target picture; performing sharpening processing on the gray scale picture to acquire a sharpened picture; determining the pixel value of each pixel point of the sharpened picture; determining the standard deviation of the pixel value of the target picture according to the pixel value of each pixel point of the sharpened picture; and if the standard deviation is lower than a preset standard deviation threshold value, then determining that the target picture is a blurred picture. The technical scheme provided in the invention makes the blurred picture identifying process relatively simple. An identifying rate for identifying a large number of pictures can be further guaranteed.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for recognizing blurred pictures. Background technique [0002] Nowadays, in people's work and life, there are more and more photographic devices that can be used, such as cameras, mobile phones with cameras, tablet computers, etc., and people can take pictures as they like. With the accumulation of time, more and more pictures are obtained by taking pictures, and more and more storage space is required. In fact, in the process of taking pictures, it is inevitable that blurred or unclear pictures will be produced. If these pictures are stored, more storage space will be wasted, and the storage space of terminals such as photographic equipment or computers is limited. In many cases, these pictures need to be deleted or otherwise processed. [0003] At present, before these blurred pictures are deleted or processed in other ways, it is necessary to ma...

Problems solved by technology

In fact, in the process of taking pictures, it is inevitable that blurred or unclear pictures will be produced. If these pictures are stored, more storage space will be wasted, and the storage space of terminals such as photographic equipment or computers is limited. In many cases, these pictures need to be deleted or otherwise processed

[0003] At present, before these blurred pictures are deleted or processed, it is necessary to manually identify which pictures are blurred pictures. If the number of pictures is large, the identification process is cumbersome and the recognition rate is low.
