[0112] Based on the first embodiment, the second embodiment of the scene change detection method of the present invention is proposed, referring to image 3 , in this embodiment, step S3000 includes:

[0113] Step S3100, when the similarity value is within a preset threshold range, convert the first spatial histogram into a first time histogram, and convert the second spatial histogram into a second time histogram;

[0114] When the similarity value is within the preset threshold range, it means that the first detected picture and the second detected picture may be the same scene, or may not be the same scene; therefore, when the similarity value is within the preset If it is within the threshold range, it is necessary to further detect and determine whether the first detected picture and the second detected picture are of the same scene. Specifically, for the first spatial histogram and the second spatial histogram respectively corresponding to the first detection picture an...

Abstract

The invention discloses a scene change detection method, which includes: acquiring a first detection picture and a second detection picture currently to be detected, and generating a first spatial histogram corresponding to the first detection picture and the second detection picture A corresponding second spatial histogram; calculating a similarity value between the first spatial histogram and the second spatial histogram; determining the first detection picture and the second spatial histogram according to the similarity value and a preset threshold range 2. Check whether the picture is the same scene. The invention also discloses a scene change detection device and a computer-readable storage medium. The present invention realizes an efficient scene change detection method, overcomes the problem of low detection efficiency of the traditional algorithm, and also converts the histogram of the space dimension into the histogram of the time dimension, further improves the detection efficiency, and realizes the detection of high Efficient, real-time detection of scene cuts in pixelated video.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a scene change detection method, device and computer-readable storage medium. Background technique [0002] Video scene change detection is the basic technology for automatic video segmentation, and many scene-related video applications such as video summarization and automatic color adjustment rely on fast and effective scene detection algorithms. Currently, many effective algorithms utilize non-global block-by-block image information, and non-color-related features such as edge detection to improve recall and reduce false positives. However, the current segmentation algorithm and the extraction of complex image features are both inefficient and cannot meet the current real-time detection needs of high-pixel video. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above...
