Directional processing of color images: theory and experimental results
TLDR
Vector directional filters are very accurate chromaticity estimators when the error is measured in the L*a*b* space, which is very close to the human perception of colors. Expand

Generalized multichannel image-filtering structures
TLDR
We introduce a new filter structure, the directional-distance filters (DDF), which combine both VDF and VMF in a novel way. Expand

Improved Speech-to-Text Translation with the Fisher and Callhome Spanish–English Speech Translation Corpus
TLDR
We introduce the Fisher and Callhome Spanish-English Speech Translation Corpus, supplementing existing LDC audio and transcripts with (a) ASR 1-best, lattice, and oracle output produced by the Kaldi recognition system and (b) English translations obtained on Amazon’s Mechanical Turk. Expand

Generative Content Models for Structural Analysis of Medical Abstracts
TLDR
This paper describes experiments with generative models for analyzing the discourse structure of medical abstracts, which generally follow the pattern of "introduction", "methods", "results", and "conclusions". Expand

Combining vector median and vector directional filters: the directional-distance filters
TLDR
We introduce a new class of filters, the directional-distance filters (DDF), which combine both VDF and VMF in a novel way. Expand

Score normalization and system combination for improved keyword spotting
TLDR
We present two techniques that are shown to yield improved Keyword Spotting (KWS) performance when using the ATWV/MTWV performance measures: (i) score normalization, where the scores of different keywords become commensurate with each other and they more closely correspond to the probability of being correct than raw posteriors; and (ii) system combination, where scores are interpolated with weights which are optimized using MTWV as the maximization criterion.

A relationship between quantization and watermarking rates in the presence of additive Gaussian attacks
TLDR
A system which embeds watermarks in n-dimensional Gaussian data and distributes them in compressed form in the presence of additive Gaussian attacks is studied. Expand
