Abstract

The invention discloses an automatic detection method of jitter of a video. The automatic detection method comprises the following steps of: a first step, selecting feature points from a video picture; a second step, tracing and matching the feature points in an adjacent frame; a third step, removing abnormal points of the feature points to obtain an inter-frame motion vector; a fourth step, extracting a video jitter frequency and video jitter amplitude features; a fifth step, extracting histogram features of an inter-frame light stream vector; and a sixth step, judging the video jitter degree through a classifier. According to the automatic detection method, any prior knowledge is not needed while judging whether the video has jitter and the automatic detection method has the advantage of a higher accuracy rate.

Description

technical field [0001] The invention can be used for digital video captured by mobile or fixed equipment such as mobile phones, digital cameras, monitoring cameras, etc., to automatically detect whether there is jitter in the digital video picture, and is specifically an automatic detection method for video jitter. Background technique [0002] Digital videos shot by mobile terminals are often accompanied by video jitter, which affects the visual quality of the video and subsequent processing effects such as target recognition. Therefore, there are currently many video stabilization methods for reducing the degree of video jitter. However, for an arbitrary digital video, it is necessary to judge the degree of video jitter before correctly selecting the correct video image stabilization method and method parameters. [0003] On the one hand, the video shake detection method can be used as a preprocessing module of the video image stabilization method. For any video, the degre...
