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 quantifying the amount of harmonic structure preservation of musical tones using different algorithms may be employed in cochlear implant devices. In this paper, a new matrix is proposed that is when 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 was be mandatory. The results show that Omran matrix is powerful in this application and illustrated higher performance of one of the utilized algorithms with respect to others.
