hello could someone help me out. I am doing 3D phase unwrapping of an
image. Could anyone send me a program. and also how to do phase
unwrapping of an image in a step by step procedure.
thank you

Hi,
I am wondering, how to find the log likelihood
ratio (LLR) random vector. My system was modeled as
Y= AX+N, where Y = [y1 y2]T; X= [x1 x2]T; A is a
square matrix , and N is [n1 n2]T. where n1 and n2 are
Gaussian iid random varibales with mean 0 and var
sigma^2.
x1 and x2 are binary random variables with in [1 -1].
for a simple model like y= x+n, I can caluclate LLR as
LLR= log(pdf(y/x=+1)/pdf(y/x=-1)) .
But , how to calulcate the in vectored case
as we have
y1= A11x1+A12x2+n1;
y2= A21x1+A22x2+n2;
Does any body have idea?
Thanks in advance.
