Function MORLET_2D_NODC
Package
filters
Short description
computes the 2-D elliptic Morlet filter given a set of
Usage
gab = MORLET_2D_NODC(N, M, sigma, slant, xi, theta, offset)
Input
N (numeric): Width of the filter.
M (numeric): Height of the filter.
sigma (numeric): Standard deviation of the envelope.
slant (numeric): Eccentricity of the elliptic envelope.
(the smaller slant, the larger angular resolution).
xi (numeric): The frequency peak.
theta (numeric): Orientation in radians of the filter.
offset (numeric, optional): 2-D vector reprensting the offset location
(default [0 0]).
Output
gab (numeric): N-by-M matrix representing the gabor filter in spatial
domain.
Description
Compute a Morlet wavelet in Fourier domain.
Morlet wavelets have a 0 DC component.
