Adaptive multi-resolution windowing technique for localized spatio-spectral analysis

Khalid, Zubair; Kennedy, Rodney; Durrani, Salman; Sadeghi, Parastoo


This paper introduces an adaptive, multi-resolution windowing technique that can be used in conjunction with the spatially localized spherical harmonic transform (SLSHT) to process signals on the 2-sphere in the spatio-spectral domain. In contrast with the standard formulation, which uses a fixed window, the new windowing technique is able to respond locally to the signal under analysis, that is, be adaptive, and also is formulated to depend on the spectral degree to give it a multi-resolution...[Show more]
