Detecting diagonal activity to quantify harmonic structure preservation with cochlear implant mapping


Omran, S (2011). Detecting diagonal activity to quantify harmonic structure preservation with cochlear implant mapping. International Journal of Robotics and Automation, 1(5):100-112.

Abstract

Matrix multiplication is widely utilized in signal and image processing. In numerous cases, it may be considered faster than conventional algorithms. Images and sounds may be presented in a multi-dimensional matrix form. An application under study is detecting diagonal activities in matrices to quantify the amount of harmonic structure preservation of musical tones using different algorithms that may be employed in cochlear implant devices. In this paper, a new matrix called "Omran matrix" has been proposed. When it is post multiplied with another matrix, the first row of the output represents indices of fully active detected diagonals in its upper triangle. A preprocessing matrix manipulation might be mandatory. The results show that the proposed matrix is powerful in this application and illustrated higher grade of harmonic structure preservation of one algorithm used for cochlear implants with respect to other algorithms.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
