Video Forensic Marking Algorithm using Peak Position Modulation
نویسندگان
چکیده
Forensic marking, a type of watermarking, is an efficient means of detecting copyright violation and tracing unauthorized access to digital content. In this paper, a new video forensic marking algorithm is proposed which uses peak position modulation (PPM) and can embed sufficient information to trace an illegal distributor. PPM uses the positions of correlation peaks, which are modulated by user information. Furthermore, a forensic mark is embedded into a 2-level 3D discrete wavelet transform (DWT) domain. Experimental results show the robustness against various attack and the capacity improvement of proposed algorithm.

Lateral Position Detection Using a Vehicle-Mounted Camera
A complete prototype system for measuring vehicle lateral position has been set up during the course of this master’s thesis project. In the development of the software, images acquired from a back-ward looking video camera mounted on the roof of the vehicle were used. The problem of using computer vision to measure lateral position can be divided into road marking detection and lateral positio...
متن کاملAssessing Behavioral Patterns of Motorcyclists Based on Traffic Control Device at City Intersections by Classification Tree Algorithm
According to the forensic statistics, in Iran, 26 percent of those killed in traffic accidents are motorcyclists in recent years. Thus, it is necessary to investigate the causes of motorcycle accidents because of the high number of motorcyclist casualties. Motorcyclists' dangerous behaviors are among the causes of events that are discussed in this study. Traffic signs have the important role of...

Due to the increase of users the efficient usage of spectrum plays an important role in digital terrestrial television networks. In digital video broadcasting, local and global content are transmitted by single frequency network and multifrequency network respectively. Multifrequency network support transmission of global content and it consumes large spectrum. Similarly local content are well ...

This paper describes a semi-automatic parking system, which can designate target position by recognizing parking lot markings. Driver is able to designate or refine the target position by drag&drop based novel user interface. Peak pair detection and clustering in Hough space recognize marking lines. Specially, one-dimensional filter in Hough space is developed to incorporate a priori knowledge ...
متن کاملBinary forensic code for multimedia signals: resisting minority collusion attacks
Digital forensic marking is a technology to discourage unauthorized redistribution of multimedia signals by embedding a unique mark into each user’s copy of the content. A powerful class of attacks on forensic marking is the collusion attack by a group of users. Recently, a new collusion attack, called the minority attack, has been proposed against forensic marking schemes with correlation-base...
