How Shifting and Scaling in Continous signals is related to Images

Started by narin October 21, 2008
Hello Everybody!

I am doing a study of wavelets. I am able to get basic idea of wavelets as
how the input signal is multiplied with a scaled and shifted windowing
function.But I am not clear of how the filtering process is carried out for
2-d matrices or images. Can anybody tell me how shifting and scaling of
wavelets in continous time signals is related to images. 

Thanks in advance!
Narin.
