A new projection method based on the row action projection (RAP) algorithm for image restoration is presented. The new implementation is computationally attractive and facilitates local adaption of projection operators. The local mean and the least L

Speech enhancement is often required prior to speech recognition and speaker identification (SI) systems. The new speech enhancement techniques described herein are based on the Pitch Mode Modulation Model (PMMM). The PMMM exploits the time-synchrony

The paper addresses the environmental mismatch problem that arises from noise and channel variabilities. A new feature mapping technique based on an optimal affine transform of the cepstrum is proposed to solve the mismatch problem observed over the

Speaker identification (SI) and speech recognition systems display a strong sensitivity to ambient noise conditions. It is known that the performance of these systems is maximized when trained under conditions that approximate the testing environment

The application of row action projections (RAPs) to the problem of acoustic echo cancellation is discussed. It is shown how RAPs, a subset of projections onto convex sets (POCSs) and a generalization of LMS, can be used to further improve the trackin

In order to create new materials which can be used as solid dielectric in high energy density capacitors, a number of insulating polymer films possessing very high dielectric constants and high breakdown strengths have been synthesized and/or modifie

A text-dependent speaker verification system based on neural tree network (NTN) phoneme model and phonetic weighting scoring method is presented. The system uses a set of concatenated NTNs trained on phonemes to model a password. In contrast to the c

The row action projection (RAP) method is used to increase the spatial resolution of images reconstructed via the filtered back projection (FBP) algorithm. An implementation of RAP is introduced which is computationally efficient and facilitates loca

In this paper we address the issues involved in implementing the Linear Programming (LP) method of image restoration in two dimensions. A modified pivot strategy is introduced in order to reduce the number of iterations. This approach is necessary du
