Video tracing method based on visible watermark

Abstract

The invention relates to the field of video tracing, in particular to a video tracing method based on a visible watermark. The video tracing method comprises the following steps: acquiring an originalvideo image, and acquiring equipment information, user information and download information; arranging the equipment information and / or the user information and / or the download information accordingto a set sequence to obtain an RGB (Red Green Blue) image of the information, namely, an image to be embedded with a watermark; and converting the original video image and the image to be embedded with the watermark into an HIS space to obtain an original video HIS image and an HIS image to be embedded with a watermark respectively, embedding the HIS image to be embedded with the watermark into the original video HIS image to obtain an HIS video image containing a watermark, and converting the HIS video image containing the watermark into an RGB space to obtain an RGB video image containing the watermark finally. Through adoption of the video tracing method, a video source can be determined rapidly and accurately; meanwhile, the defects of video resource management work can be found immediately; and a decision is made for later video resource management work arrangement.

Description

technical field [0001] The invention relates to the field of video source tracing, in particular to a video source tracing method based on an explicit watermark. Background technique [0002] Since the construction of the first batch of 3111 pilot city monitoring systems in the country in 2005, the construction of safe cities in my country has entered a climax period. Video surveillance is spread all over the streets and alleys. At present, key security monitoring areas, such as road intersections, residents Residential areas, urban roads, commercial centers, entertainment venues, station plazas, key units and other places implement remote network real-time monitoring to keep abreast of on-site traffic flow, people flow and abnormal situations, and perform video backup. At the same time, video surveillance has also played an increasingly important role in the handling of cases by public security organs. [0003] Due to the prominent role of video surveillance in the process ...

AI Technical Summary

Problems solved by technology

[0003] Due to the prominent role of video surveillance in the process of handling cases, the use of video resources is more frequent, resulting in frequent leaks of confidential and sensitive videos. However, the source of leakage of leaked confidential and sensitive videos cannot be found, and it is difficult to determine the management of video resources. work flaws
