A generalized musical-tone generator with application to sound compression and synthesis
1997 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2002A musical-tone generator based on physical modeling of sound production mechanisms is presented. For the purpose of making this scheme general for a wide class of musical instruments, the nonlinear part of the tone-generator is modeled by a neural network.

Discrimination of MP3-compressed musical instrument tones.
The Journal of the Acoustical Society of America, 2010Eight musical instrument tones were compressed using an MP3 codec to determine how the detection of compressed sounds varies with bit-rate and instrument. Sounds with harmonically flattened frequencies were compressed with bit-rates of 32, 40, 48, 56, 64, 80, 96, 112, 128, and 160 kbps.

Evaluation of algorithms for lossless compression of continuous-tone images
Journal of Electronic Imaging, 2002Lossless image compression algorithms for continuous- tone images have received a great deal of attention in recent years. However, reports on benchmarking their performance have been limited. In this paper, we present a comparative study of the follow- ing algorithms: UNIX compress, gzip, LZW, Group 3, Group 4, JBIG, old lossless JPEG, JPEG-LS based ...

A Proficient Algorithm for Compression and Storage of Two-Tone Image
Asian Journal of Computer Science and Technology, 2016Since 1990s , there has be a swift, increase in computers, storage media and digital image taking devices, which enables a large number of digital information and store in computer readable formats. Image compression is an important issue in internet, mobile communication, digital library and other applications. Image compression refers to represent an

Deterministic selection of pilot tones for compressive estimation of MIMO-OFDM channels
2015 49th Annual Conference on Information Sciences and Systems (CISS), 2015This paper addresses the problem of channel estimation in multiple-input and multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) systems for the case when the underlying multipath channel is approximately sparse in the angle-delay domain.

The ISO/CCITT standard for continuous-tone image compression
IEEE Global Telecommunications Conference, 1989, and Exhibition. 'Communications Technology for the 1990s and Beyond, 2003The ISO/CCITT Joint Photographic Experts Group is in the process of developing an international standard for general-purpose, continuous-tone still-image compression. A brief history is presented as background to a summary of the past year's progress, which was highlighted by definition of the overall structure of the proposed standard.

Efferent-induced change in human cochlear compression and its influence on masking of tones
Neuroscience Letters, 2010Several lines of evidence suggest that medial olivocochlear (MOC) efferent neurons modify cochlear output to improve signal detection in noise. In animal models, stimulation of MOC efferents reduces the amount of compression in basilar membrane (BM) growth functions.
