    'OPTICOMP' COMPUTER-MAIL LIST ON OPTICAL COMPUTING AND HOLOGRAPHY 
    *---------------------------------------------------------------* 

I would like to announce the opening  of a new computer mailbox, or list, 
named OPTICOMP.   This list  will be dedicated  to Optical  Computing and 
Holography.  Specifically, subjects such as 

(*) Holographic  displays,  including  true holographic  3-D  display  of 
    computer generated images, 

(*) Optical (both  analog and digital) information  processing, including 
    pattern   recognition,   algorithms  for   rotation/scale/perspective 
    invariant  recognition through  correlation,  realization of  digital 
    processing  machines with  optics, communication-intensive  computing 
    architectures etc. 

(*) Optical  realizations  of  neural  networks  and  associative  memory 
    systems. 

Those of you who are interested in getting this newsletter are invited to 
write to me to one of the E-mail addresses below. 

                             Yours,

Subject: resampling filter references wanted 

 
I'm doing some research on filters for ideal resampling of one discrete 
image into another according to an arbitrary 2-D distortion. 
I map from a source image with domain (u,v) to a destination image with 
domain (x,y) according to user-supplied functions x=x(u,v), y=y(u,v). 
The mapping is arbitrary in general, but affine is an important (easy) case. 
I want to minimize aliasing due to resampling.  Quality filtering for highly 
distorted mappings is vital (my application is texture mapping for computer 
graphics). 
This topic is also called "interpolation" and "multirate DSP" by some. 

Any recommendations of books/journal articles would be most appreciated! 
Please email them to me, as I don't normally read this list. 

thanks,
