Split-band speech compression based on loudness estimation
Visar Berisha,Andreas Spanias +1 more
TL;DR: In this article, a frame is received that has the wideband audio signal and the high band signal is analyzed to determine whether it is perceptually relevant to the low band signal.
Proceedings ArticleDOI
Speech processing using higher order statistics
TL;DR: The potential use of third-order statistics (TOS) in speech processing applications is examined and the TOS-based AR estimation algorithm is used to estimate the parameters of the short-term prediction filter of a code excited linear prediction (CELP) algorithm.
Proceedings ArticleDOI
Optical flow for compressive sensing video reconstruction
TL;DR: A reconstruction method is presented which fully utilizes optical flow information to increase the quality of reconstruction and the performance of the algorithm on existing datasets is evaluated.
Journal ArticleDOI
A hybrid transform method for analysis/synthesis of speech
TL;DR: A hybrid transform method for analysis/synthesis and coding of speech signals is proposed, which produces natural sounding speech which is indistinguishable from the original at 16 kbit/s and highly intelligible at 9.6 k bit/s.

Ensemble Sparse Models for Image Analysis
TL;DR: This paper proposes and analyzes the framework of ensemble sparse models, and demonstrates their utility in image restoration and unsupervised clustering, and shows that the proposed model performs better than baseline approaches in several standard datasets.
