Wavelet Toolbox

Discrete Wavelet Packet 2-D options.

Compression using a global threshold.

X is the image to be compressed and WPT is the wavelet packet decomposition structure of the image to be compressed.

THR = wthrmngr('wp2dcompGBL','bal_sn',WPT)

THR = wthrmngr('wp2dcompGBL','rem_n0',X)

THR = wthrmngr('wp2dcompGBL','sqrtbal_sn',WPT)

De-noising using a global threshold.

WPT is the wavelet packet decomposition structure of the image to be de-noised.

THR = wthrmngr('wp2ddenoGBL','sqtwologuwn',WPT)

THR = wthrmngr('wp2ddenoGBL','sqtwologswn',WPT)

THR = wthrmngr('wp2ddenoGBL','sqrtbal_sn',WPT)

THR = wthrmngr('wp2ddenoGBL','penalhi',WPT)
see wbmpen with ALFA = 6.25

THR = wthrmngr('wp2ddenoGBL','penalme',WPT)
see wbmpen with ALFA = 2

THR = wthrmngr('wp2ddenoGBL','penallo',WPT)
see wbmpen with ALFA = 1.5
