Color video signal processing with median filters
IEEE Transactions on Consumer Electronics, 1992Methods of applying median filtering for three-dimensional video signals were studied and are compared. Median operation and RGB- versus YUV-domain processing are discussed. An introduction to various ordering methods in median-based multidimensional filtering is given. The various 3-D median processing methods and the effect of the conversion from the

Digital signal processing for video applications
IEEE Journal of Solid-State Circuits, 1983Digital video signal processing is one result of the fast progress in NMOS-VLSI techniques. The attractions of using digital data processing methods in an analog application field are the availability of CAD tools for the design of digital ICs and the integration of digital filter functions. Besides the key components such as microcomputers, A/D, and D/

Video Recording with New Signal Processing
IEEE Transactions on Consumer Electronics, 1985Video recording systems such as VTRs generally use an emphasis method in signal processing to reduce noise generated in FM recording and reproduction, using a pre-emphasis circuit and a de-emphasis circuit. In recording, the high frequency components of the video signal are emphasized by the pre-emphasis circuit and, in reproduction, the emphasized ...

HiveFlex-Video VSP1: Video Signal Processing Architecture for Video Coding and Post-Processing
Eighth IEEE International Symposium on Multimedia (ISM'06), 2006As mobile displays proliferate across the world, and fixed video displays expand in size, consumers demand enhanced visual experiences while watching such displays. Competitive low-end to high-end markets are migrating to high-definition (HD) output displays driven by consumer demand. In order to generate high quality visual experiences on HD displays,

Sync signal processing for asynchronously sampled video signals
2000 IEEE International Symposium on Circuits and Systems. Emerging Technologies for the 21st Century. Proceedings (IEEE Cat No.00CH36353), 2002Digital sync signal processing for asynchronously digitized video signals is presented. A simplified matched filter for sync extraction and a linear prediction method for sync pulse filtering improves image stability significantly in comparison with a conventional phase-locked-loop (PLL) approach.

Asymptotic limits of video signal processing architectures
IEEE Transactions on Circuits and Systems for Video Technology, 1995This paper analyzes the effects of technology scaling on video signal processing (VSP) architectures. We evaluate the processor, the memory, and the interconnect delays in terms of sophisticated delay models (that take into account deep-sub-micron device characteristics) and study how the response times of these logic components are affected when the ...
