Fast CELP coding based on algebraic codes
TLDR
The paper describes a related scheme, which allows real time implementation on current DSP chips, and the very efficient search procedure in the codebook is achieved by means of a new technique called "backward filtering" and the use of algebraic codes.
16 kbps wideband speech coding technique based on algebraic CELP
TLDR
An efficient procedure for searching such a large codebook deploying a focused search strategy, where less than 0.1% of the codebook is searched with performance very close to that of a full search is described.
Touching and hearing GUI's: design issues for the PC-Access system
TLDR
Two versions of PC-Access are proposed: one which offers sound feedback with an enhanced drawing tablet and another in which tactile stimuli are synthesized by a haptic pointing device.
Bayesian Filtering and Anonymous Sensors for Localization in a Smart Home
TLDR
A solution to localize the occupant thanks to Bayesian filtering and a set of anonymous sensors disseminated throughout the house and the preliminary results are encouraging: location estimation exceeds 85% certainty in most cases.
Location Estimation in a Smart Home: System Implementation and Evaluation Using Experimental Data
TLDR
A solution to localize the occupant thanks to Bayesian filtering and a set of anonymous sensors disseminated throughout the house and is independent of the occupant's profile and behaves well in presence of noise.
Subband decomposition: an LMS-based algorithm to approximate the perfect reconstruction bank in the general case
An algorithm based on least mean squares (LMS) is described. Given an arbitrary invertible decomposition/decimation process, the algorithm will find the finite impulse response reconstruction filters
Cooking risk analysis to enhance safety of elderly people in smart kitchen
TLDR
The pertinent parameters determined are: concentrations of gases in the cooking smoke, ambient temperature, utensil temperature, burner temperature, relative humidity, and presence of an object on burner.
Toward Pervasive Computing System to Enhance Safety of Ageing People in Smart Kitchen
TLDR
The hardware architecture of the cooking-safe system that targets enhancing safety of ageing people while cooking is presented, based on insightful cooking risk analysis that enables to determine the pertinent parameters to be monitored and measured while cooking.
The 'stretched'-Golay and other codes for high-SNR finite-delay quantization of the Gaussian source at 1/2 bit per sample
TLDR
The stretched Golay codes are shown to outperform previously published results for block lengths 32, 40, 56, and 64 and make these techniques attractive for applications such as low-bit-rate coding of speech.
