This algorithm is available for both gray scale and true color images in the Wavelet Toolbox as an option for wcompress

try this code
clc;
close all;
clear all;
I=imread('wpeppers.jpg');
figure('Name','inputimage'),imshow(I)
figure,
% compression
[cr,bpp] = wcompress1('c',I,'woodstatue.wtc', ...
'spiht','cc','klt','maxloop',11,'plotpar','plot');
%un compression
Xc = wcompress1('u','woodstatue.wtc');
delete('wpeppers.wtc')
figure,imshow(Xc);
