Safe math gabor filter

WebA 2D Gabor filter is a product of an elliptical Gaussian in any rotation and a complex exponential representing a sinusoidal plane wave . The sharpness of the filter is controlled through the major axis and minor axis, which is perpendicular to the wave. The filter can be defined as where ƒ is the central frequency of the sinusoidal plane WebNov 17, 2010 · The function accepts scalar inputs only, and each call generates one filter. The filter generated is always real. Should you wish to build a complex Gabor filter, you may use (0 phase) + j(pi/2 phase). Filtering can be performed using conv2( ) or imfilter( ).
