Multimedia Software reuse instances are found from an execution trace through a process of quantization, discovery, and synthesis. Quantization includes mapping n-dimensional vectors that correspond to instructions, live-in states, and live-out… S. H. Park, O. Simeone, O. Sahin, and S. Shamai, “Fronthaul compression for cloud radio access networks: Signal processing advances inspired by network information theory,” IEEE Signal Process. The first step of the algorithm finds the optimum disparity vector for extremely large block sizes with a very large search window, with an initial guess of the disparity vector.

Lossless image compression system A method, system, and manufacture are provided, for use in connection with data processing and compression, for quantizing a string of data values, such as image data pixel values. The Large Text Compression Benchmark and the similar Hutter Prize both use a trimmed Wikipedia XML UTF-8 data set. Due to the increasing demand for better speech algorithms, several standards were developed, including MPEG, MP3, etc. Data compression using transformations such as the DCT and the DFT are the basis for many coding standards such as JPEG… In vector quantization the number of vectors used to construct the codebook is always an undefined problem, there is always a compromise between the number of vectors and the quantity of information lost during the compression.
However the quantization of 181/256 causes system quantization error from 80dB to 30+dB,
