viewWTLM(2) Scilab Function viewWTLM(2)
NAME
viewWTLM - Vizualises the local maxima lines of a CWT
Author: Paulo Goncalves
Displays the local maxima of a continuous wavelet transform
Usage
viewWTLM(maxmap[,scale,wt])
Input parameters
o maxmap : 0/1 matrix [N_scale,N] Indicator matrix of the local
wavelet coefficients maxima
o scale : real vector [1,N_scale] Analyzed scale vector
o wt : Complex matrix [N_scale,N] Wavelet coefficients of a continu-
ous wavelet transform (output of FWT or contwt)
See also:
findWTLM, viewmat, contwt, cwt
Example:
N = 2048 ; H = 0.3 ; Q = linspace(-4,4,11) ;
[x] = fbmlevinson(N,H) ;
[wt,scale] = cwt(x,2^(-6),2^(-1),36,0) ;
[maxmap] = findWTLM(wt,scale)
Vizualisation in Matlab:
viewWTLM(maxmap,scale,wt) ,
axis([1024 - 64 1024 + 64 0 log2(max(scale))]) ,
Vizualisation in Scilab: Not implemeted yet!...
