Parameters

- im:

image matrix (e.g., output of "toimage")

- t (optional):

time instants (e.g., output of "toimage")

- threshold:

is the visualization threshold, in % default: threshold=5;

- fs:

sampling frequency

Examples

s = rand(1,512,'normal');
imf = emd(s);
[A,f,tt] = hhspectrum(imf(1:$-1,:));
[im,tt]=toimage(A,f);
disp_hhs(im);
