Please cite this article in press as: S.P. Sabatini Image Understand. (2010), doi:10.1016/j.cviu.2 The problem of representing the visual signal in the harmonic space guaranteeing a complete characterization of its 2D local structure is investigated. Specifically, the efficacy of anisotropic versus isotropic filtering is analyzed with respect to general phase-based metrics for early vision attributes. We verified that the spectral information content gathered through channeled oriented… CONTINUE READING
