Ctfrreas

Time Frequency Representation reassignment

Calling Sequence

TFR_reas = Ctfrreas(TFR, field_time, field_freq)

Parameters

TFR :

Real matrix, TFR to be reassigned

field_time :

Real Complex matrix with same size as TFR. Time components of the field of reassignment vectors

field_freq :

Real matrix with same size as TFR. Frequency components of the field of reassignment vectors

TFR_reas :

Reassigned TFR

Description

Reassigns the pixels of a TFR, given a field of reassignment vectors.

Examples

[SP_reas,SP,field] = Ctfrrsp(hilbert(sin(2*%pi*0.25*(1:128)))+0.5*rand(1,128,'normal'));
SP_reas2 = Ctfrreas(SP,real(field),imag(field));
grayplot(1:128,1:128,SP_reas');
scf(); grayplot(1:128,1:128,SP_reas2');
