چکیده
This paper describes hardware that has been built to compress video in real time using full-search vector quantization (VQ). This architecture implements a diierential-vector-quantization (DVQ) algorithm and features a special-purpose digital associa-tive memory, the VAMPIRE chip, which has been fabricated in 2m CMOS. We describe the DVQ algorithm, its adaptations for sampled NTSC composite-color video, and details of its hardware implementation. We conclude by presenting images drawn from real-time operation of the DVQ hardware.

Gradient algorithms for designing predictive vector quantizers
A predictive vector quantizer (PVQ) is a vector extension of a predictive quantizer. It consists of two parts: a conventional memoryless vector quantizer (VQ) and a vector predictor. Two gradient algorithms for designing a PVQ are developed in this paper: the steepest descent (SD) algorithm and the stochastic gradient (SG) algorithm. Both have the property of improving the quantizer and the pre...
متن کاملEnhanced dynamic codebook reordering for advanced quantizer structures
Conventional dynamic codebook reordering can often significantly enhance the achievable compression efficiency in simple one-stage vector quantization. When applied to more advanced quantizer structures, such as multi-stage vector quantizers, the performance of the technique becomes worse. This paper describes in detail an enhanced approach for dynamic codebook reordering that improves the perf...
متن کاملAn adaptive-search residual vector quantizer for airborne reconnaissance
A lossy image compression algorithm designed for highspeed, high quality data applications is described. The algorithm consists of a vector quantizer followed by a modified Huffman entropy encoder. The quantizer is a meanremoved, adaptive-search, residual vector quantizer. A few details of a high-speed hardware implementation for reconnaissance are given, as well as an example of the performanc...
متن کاملConstruction of a pIX-modified Adenovirus Vector Able to Effectively Bind to Nanoantibodies for Targeting
Current targeting strategies for genetic vectors imply the creation of a specific vector for every targeted receptor, which is time-consuming and expensive. Therefore, the development of a universal vector system whose surface can specifically bind molecules to provide efficient targeting is of particular interest. In this study, we propose a new approach in creating targeted vectors based on t...
متن کاملVector Quantization and the FSCL Training
An artiicial neural network vector quantizer is developed for use in data compression applications such as Digital Video. Two techniques are employed to improve the performance of the encoder. First, Diierential Vector Quantization (DVQ) is used to signiicantly improve edge delity. Second, an adaptive ANN algorithm known as Frequency-Sensitive Competitive Learning is used to develop an frequenc...
