Function MORLET_2D_PYRAMID

Package

Short description

Usage

    gab = MORLET_2D_PYRAMID(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): excentricity 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): 2-by-1 Vvector index of the row and column of the
       center of the filter (if offset is [0,0] the filter is centered in
       [1,1])

Output

    gab (numeric): N-by-M matrix representing the gabor filter in spatial
       domain.

Description

    Compute a Morlet wavelet in spatial domain. 
    Morlet wavelets have a 0 DC component.
