Fast anisotropic gauss filtering
WebStep 1: SIMD 1-dimensional Gaussian blur. Step 2: transpose. Step 3: Repeat step 1. It is best done on small blocks, as a full-image transpose is slow, while a small-block transpose can be done extremely fast using a chain of PUNPCKs ( PUNPCKHBW, PUNPCKHDQ, PUNPCKHWD, PUNPCKLBW, PUNPCKLDQ, PUNPCKLWD ). Share. WebThis paper proposes an energy filtering method based on time-domain extended image sequences, which is a typical application such as a star tracker. The energy variations of the spot in continuous sequences are analyzed, and the energy is filtered at pixel level.

WebSep 17, 2013 · In [ 6 ], the authors proposed a method to decompose the anisotropic Gaussian filter, which is a critical component in Gabor wavelet formulation. In the method, 2D filtering is performed by first applying a 1D Gaussian filter in the x direction, followed by another 1D Gaussian filter along a line in a particular orientation. WebThe anisotropic Gaussian filtering method allows fast calculation of edge and ridge maps, with high spatial and angular accuracy. For tracking applications, the normal anisotropic convolution scheme is more …
