Speech Compression Using Linear Predictive Coding(lpc)
One of the most powerful speech analysis techniques is the method of linear predictive analysis. This method has become the predominant technique for representing speech for low bit rate transmission or storage. The importance of this method lies both in its ability to provide extremely accurate estimates of the speech parameters and in its relative speed of computation. The basic idea behind l...
متن کاملAn Efficient Time Domain Speech Compression Algorithm Based on LPC and Sub-Band Coding Techniques
Speech compression is a mature technology with many applications. Over the past decade, huge advances have been made in the area of speech coding for reduced bit-rate transmission. With perceptual audio coding, the signal is coded efficiently using a psychoacoustic model, as in MPEG standards. In this paper, two well known algorithms, LPC (Linear Predictive Coding) and subband coding are combin...
متن کاملAn 800bps VQ Based LPC Voice Coder
The idea of applying vector quantization (VQ) to linear prediction coding (LPC) to realize a very low bit-rate speech coder with reasonable speech quality is investigated in this research. Instead of encoding LPC parameters directly, line spectral frequency (LSF) coefficients are obtained through a transformation of LPC and then encoded via VQ in the proposed scheme. In order to utilize the int...
متن کاملSubjective Evaluation of an Edge-based Depth Image Compression Scheme
Multi-view three-dimensional television requires many views, which may be synthesized from two-dimensional images with accompanying pixel-wise depth information. This depth image, which typically consists of smooth areas and sharp transitions at object borders, must be consistent with the acquired scene in order for synthesized views to be of good quality. We have previously proposed a depth im...
متن کاملAn Edgebreaker-based efficient compression scheme for regular meshes
One of the most natural measures of regularity of a triangular mesh homeomorphic to the two-dimensional sphere is the fraction of its vertices having degree 6. We construct a linear-time connectivity compression scheme build upon Edgebreaker which explicitly takes advantage of regularity and prove rigorously that, for sufficiently large and regular meshes, it produces encodings not longer than ...
