AI Technical Summary

Problems solved by technology

At present, there are common problems such as incomplete targets and ghost images in video summarization.
Moreover, the video after the summary disrupts the timing logic of the target in the original video. If users want to know the real situation of a certain target, they need to view it with the help of the original video. Therefore, how to directly jump from the summary video to the original video to view the target The original situation is also a problem that needs to be solved

Embodiment Construction

[0045] Such as figure 1 As shown, the steps of the embodiment of the present invention consist of background modeling, moving object extraction, moving object tracking, moving object correction, abstract synthesis, and video indexing. The specific steps are as follows:

[0046] 1. Background modeling

[0047] The background modeling module can use various image background modeling algorithms, including color background models and texture background models. The idea of ​​a color background model is to model the color value (grayscale or chromatic) of each pixel in an image. If there is a large difference between the pixel color value on the current image coordinate (x, y) and the pixel color value on (x, y) in the background model, the current pixel is considered to be the foreground, otherwise it is the background.

[0048] The background modeling module of this embodiment uses the Gaussian mixture background algorithm in the color background model. Smoothly approximates d...

Abstract

The invention relates to a video abstract generating and indexing method. The video abstract generating and indexing method comprises the following steps of (1) conducting background modeling on a target image in an original video, and achieving background extraction; (2) conducting comparative segmentation on a current image and a background model, and determining movement targets according to a comparison result; (3) matching space information distributed between frames with characteristics of the targets separated from each image, achieving target tracking and recording the movement trails of the targets; (4) correcting the positions of the targets in the images in a sequence; (5) allowing the background to be overlaid with the movement targets to form a short video, and recording abstract video data to form an index data file. The video abstract generating and indexing method has the advantages that after the movement targets are tracked, the tracking success rate is guaranteed, the quality of a generated video abstract is improved greatly, and the video indexing function can meet the requirements that users view the video rapidly and view the original video conveniently so as to view actual situations completely.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video abstract generation and indexing method. Background technique [0002] With the vigorous development of multimedia technology and video acquisition technology, video surveillance, image compression coding and streaming media technology are gradually evolving, and video surveillance technology is more and more widely used in daily life, making video surveillance not only limited to safety precautions, Instead, it has become an effective means of supervision for all walks of life, and the flexibility of its application field has gone far beyond the scope defined by traditional security monitoring. However, the video surveillance video has the characteristics of large amount of stored data and long storage time. The traditional method of finding clues and obtaining evidence through video requires a lot of manpower, material resources and time, and the efficiency is ...
