Visual analysis of corrupted video data in video event data recorders
2017 IEEE Conference on Dependable and Secure Computing, 2017With the rapid proliferation of video event data recorders (VEDRs), video file data from VEDRs are often used as the primary evidence in many fields, such as law enforcement. In this paper, we propose a method for reconstructing corrupted video files and capturing key events recorded in the video file for use as valid evidence.

A magnifier tool for video data
Proceedings of the SIGCHI conference on Human factors in computing systems - CHI '92, 1992We describe an interface prototype, the Hierarchical Video Magnifier, which allows users to work with a video source at fine-levels of detail while maintaining an awareness of temporal context. The technique allows the user to recursively magnify the temporal resolution of a video source while preserving the levels of magnification in a spatial ...

Video Assist: a customizable tool for analyzing video data
Proceedings of the Thirtieth Hawaii International Conference on System Sciences, 2002Analyzing real world events captured in video is often a very time consuming and labor intensive process. The paper describes Video Assist, a software tool designed to assist encoding and analyzing actions recorded on video tape. It presents the design rationales underlying its features such as: customizable objects and their attributes, their ...

Efficient 2D Video Coding of Volumetric Video Data
2018 7th European Workshop on Visual Information Processing (EUVIP), 2018Point clouds for immersive media technology have received substantial interest in the recent years. Such representation of 3D scenery provides freedom of movement for the viewer. But transmitting or storing such content requires large amount of data and it is not feasible on today's network technology.

Visualising and Clustering Video Data
2007We review a new form of self-organizing map which is based on a nonlinear projection of latent points into data space, identical to that performed in the Generative Topographic Mapping (GTM) [1]. But whereas the GTM is an extension of a mixture of experts, this model is an extension of a product of experts [6].

Advances in data compression are creating new possibilities for applications combining digital audio and digital video. These applications, such as desktop authoring environments and educational or training programs, often require access to collections of audio/video material. This paper introduces audio/ video, or “AV”, databases and discusses the key

Reversible Data Hiding for Video
2018Difference expansion (DE) and histogram modification (HM) are efficient ways for reversible data hiding (RDH) into digital video. In most occasions, the reversibility of an algorithm cannot be confirmed until the data extracting experiments have been carried out, it means the design of a reversible data hiding algorithm lacks theoretical guidance.

Towards structure discovering in video data
Journal of Experimental & Theoretical Artificial Intelligence, 2005Digital images and video clips are becoming popular due to the increase in the availability of consumer devices that capture them. Digital content is also growing over the Internet. Applications that benefit from video are education and training, marketing support, medical, etc.

Video Data Modeling and Querying on Surveillance Videos
2006 IEEE 14th Signal Processing and Communications Applications, 2006To easily access the video content and to manage the huge video archieves, powerful video data models are required. Video data model and its supported queries may change the application requirements. In this study, we present a video data model and query types for surveillance videos.

Diagnostic Video Data Processing
IRE Transactions on Medical Electronics, 1960Computers have been built which can handle spatial problems. A particularly interesting application of the spatially oriented computer is to ``read'' chest X-ray photofluorograms and to separate the obviously abnormal chest films from the normal chest films. Preliminary studies of such a computer will be described.
