We investigate the benefits of evaluating Mel-frequency cep-stral coefficients (MFCCs) over several time scales in the context of automatic musical instrument identification for signals that are monophonic but derived from real musical settings. We define several sets of features derived from MFCCs computed using multiple time resolutions, and compare their(More)
The Radon transform (RT) on straight lines deals as mathematical foundation for many tomographic modalities (e.g. X-ray scanner, Positron Emission Tomography), using only primary radiation. In this paper, we consider a new RT defined on a pair of half-lines forming a letter V, arising from the mod-eling a two-dimensional emission imaging process by Comp-ton(More)
