WebApr 12, 2024 · This paper presents a BSS-VQ codebook search algorithm for ISF vector quantization in the AMR-WB speech codec. Using a combination of a fast locating technique and lookup tables, an input vector is efficiently assigned to a search subspace where a small number of codeword searches is carried out and the aim of remarkable search load … WebFirst, we consider the design of scalar channel magnitude quantization codebook and prove that the asymptotically optimal quantization levels are uniformly spaced in dB scale. Such optimality does not depend on the the channel magnitude distribution, as long as some regularity conditions are satisfied. Web0.97%. 1 star. 0.73%. From the lesson. Image Compression. In this module we cover fundamental approaches towards lossy image compression. Topics include: scalar and vector quantization, differential pulse-code modulation, fractal image compression, transform coding, JPEG, and subband image compression.
