Linear Extended Whitening Filters
In this paper we present a class of linear whitening filters termed linear extended whitening filters (EWFs) which are whitening filters that have desirable secondary properties and can be used for simplifying algorithms, or achieving desired side-effects on given secondary matrices, random vectors or random processes. Further, we present an application of EWFs for simplification of QR decompos...
متن کاملTooth whitening in children.
Although there are several case reports of vital tooth bleaching in children, there is limited clinical trial evidence of the safety or efficacy of this practice. Accordingly, a new clinical trial was conducted to evaluate the effects of 2 different bleaching systems, a 6.5% hydrogen peroxide strip system and a 10% carbamide peroxide tray system, in a population of preteens and teens. A total o...
متن کاملRecursive Whitening Transformation
Recently in speaker recognition, performance degradation due to the channel domain mismatched condition has been actively addressed. However, the mismatches arising from language is yet to be sufficiently addressed. This paper proposes an approach which employs recursive whitening transformation to mitigate the language mismatched condition. The proposed method is based on the multiple whitenin...
متن کاملOptimization-based Whitening
In natural image understanding, the whitening step plays an important role, especially within many unsupervised feature learning algorithms. Examples of these algorithms include ICA, TICA, Auto-encoder, and so forth. Current whitening techniques include Principal Component Analysis (PCA) and Zero-phase Component Analysis (ZCA). However, the drawbacks of these approaches are obvious: the time co...
متن کاملTooth whitening: concepts and controversies.
Today's society dictates that it is the norm for people to have straight, white teeth. The demand therefore for tooth whitening in dental practice has increased exponentially over the last decade. A common approach to achieving this goal is by bleaching. This article discusses clinical aspects of dental bleaching by providing an evidence-based review of current literature. Topics covered includ...
