摘要: The hyperspherical de la Vallee Poussin kernel v k (ω) = C(k) cos 2k (ω/2) is introduced as a simple standard orientation density function for texture modeling. finiteness of its harmonic series expansion advantageously distinguishes it from other known functions. Given halfwidth, the allows, example, to tabulate degree into harmonics required exact representation.
