Embodiment Construction

[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] In order to solve the problem that the prior art cannot automatically detect blurred video images, embodiments of the present invention provide a method and device for detecting blurred video images.

[0034] Such as figure 1 As shown, the detection method of the blurred video image provided by the embodiment of the present invention includes:

[0035] Step 101, decoding video content to acquire multiple video frames.

[0036] Step 102, obtain the variance value corresponding to each video frame respectively.

[0037] In this embodiment, step 102 may specifically include the following steps:

[0038] First, the mean value of each video frame is obtained separately according to formula (1):

[0039] A...

Abstract

The embodiment of the invention, which relates to the signal processing technology, provides a detection method and apparatus for a blurred video image. Therefore, a problem that a blurred video image can not be detected automatically in the prior art can be solved. According to the technical scheme, the method comprises: decoding a video content to obtain a plurality of video frames; obtaining a variance value corresponding to each video frame; and according to the variance value corresponding to each video frame, obtaining a blurred video image frame included by the video content. According to the embodiment of the invention, the method and apparatus can be applied to editing processing of a video content.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a method and device for detecting blurred video images. Background technique [0002] With the advancement of technology and the improvement of people's living standards, more and more people like to record life fragments in the form of video. However, in the actual shooting process, due to the limited shooting level of the user, for example: the user shakes during the shooting process or the shooting speed is too fast, etc., blurred video images often appear in the captured video content, which affects the viewing of the entire video Effect. [0003] At present, a technical problem that needs to be solved urgently by those skilled in the art is that the prior art does not provide a technology capable of detecting blurred video images, and users can only artificially judge whether there are blurred video images in the process of watching videos.
