Problems solved by technology

However, the above method is sensitive to light changes. Even if there is only a light change between two video frames, the gray histogram of the video frame will change greatly. Therefore, when the above method is used to detect video scene switching, the false detection rate is high.

Embodiment Construction

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0057] figure 1 It is a schematic flowchart of a video scene switching detection method provided by an embodiment of the present invention, and the method includes:

[0058] S101: Obtain the block sequence measure feature vector V of the first video frame p in the target video sequence p .

[0059] Among them, V p ={V p [0],V p [1],...,V p [N]}, N>0, 0, 1, ..., N is: the numbering of (N+1) divided blocks corresponding to the video frame determined according t...

Abstract

The embodiment of the invention discloses a video scene switching detection method and device, and relates to the technical field of video processing. The method includes the steps that a partitioning sequence measurement feature vector Vp of a first video frame p in a target video sequence is acquired; a partitioning sequence measurement feature vector Vq of a second video frame q in the target video sequence is acquired; the distance D (Vp and Vq) between Vp and Vq is calculated; whether the distance obtained after calculation meets a preset distance requirement or not is judged; if yes, it is judged that video scene switching is generated between the first video frame p and the second video frame q. By the application of the scheme, after light in video content changes, the false drop rate of video scene switching can be decreased.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a method and device for detecting video scene switching. Background technique [0002] Video scene switching refers to a phenomenon in which the image content corresponding to two adjacent video frames changes greatly according to the display sequence of the video frames. Common video scene switching includes: the image content of two adjacent frames is completely different, the image content of the current video frame is greatly shifted in a certain direction relative to the image content of the previous video frame, and the image content of the current video frame is the same as that of the previous video frame. The fusion of the image content of a frame with the image content of other video frames and so on. Video scene switching generally occurs when the camera shooting angle changes suddenly, the subject moves violently, or video source clips are spliced ​​together...
