Biomedical Signals Local Maxims Detection Using Time Frequency Transforms

Abstract

The wealth of genomic data currentlyavailable in online databases has caused a need fornew algorithms and analysis techniques to interpretgenomic data. In this paper we explore techniques forlocating critical genomic data in protein sequences andfor estimating the similarity between proteins. Byconverting genomic data into numeric sequencessignal processing methods can be applied to processthe resulting information. We demonstrate the use ofthe Short-Time Fourier Transform and theContinuous Wavelet Transform in locating importantamino acid properties contained in protein sequences.
