Ridge_AWT

Ridges of an Analytic Wavelet Transform

Calling Sequence

localmaxima = Ridge_AWT(m,par,ABS);

Parameters

Inputs:

m :

input matrix

par :

parameter, 2*par is how many neighbours to compare

ABS :

flag, compare by absolute value(1) or not(0)

Outputs:

localmaxima:

local maxima of every column, binary matrix same size as m.

Description

see section 4.4.2 of Mallat's book Algorithm Get the local maxima first, then compare with original value
