hi thanks a lot for your codes

now i have a problem

for nlevels = 2 the mkl is [2 0;0 2] and the Quincunx sampling is matrices is q1 = [1, -1; 1, 1] can i use dup(x, step,phase) for mk1 and qupz(x, type) for q1 in matlab to implement them?

i can't undrestand zconv2.c function if you program this function in matlab my problems solved

The demo program works well only for square matrix image
( example 512x512).BUT for a image of different dimension for example 128x104 size image, it shows error in the symext.m . Anybody please clear...

For Linux/Unix users:
there are comments in C++ style within zconf2.c, atrousc.c and zconf2s.c which will lead to the error (for gcc version 4.1.3):
error: expected expression before ‘/’ token
remove all comments containing // or substitute them by ANSI-C comments. And try again.

I AM USING SAME TOOLBOX. I HAVE ONE QUERY REARDING THIS

i want to increase directional subbands. i.e. for Nlevel=2 i get 4 subbands. but in that 4 subbands i want to increase directional subbands. so is it possible? if yes then how we can change that parameter. because if we write nlevel=[0,1,2] it means it gives results upto 2 level but how to change/increase directional componets? please reply as soon as possible
