Witryna10 cze 2024 · ABSTRACT. Aiming at the problem that the amplitude frequency characteristic and the group delay characteristic of the traditional fractional delay filter deteriorate at the higher frequency, a fractional delay filter based on Hermite interpolation polynomial is proposed to approximate the ideal non-integer delay filter … WitrynaWhat is Hermite filter? Two-dimensional Hermite filters provide a simple description of third- and fourth-order statistics of natural images across a range of scales. This simplification is a consequence of the high degree of symmetry of this orthogonal basis set, and the phase, amplitude, and luminance characteristics of natural images. ...
