From: Handprint Sample Form Account <hsf@magi.ncsl.nist.gov>
Organization: National Institute of Standards and Technology
	formerly National Bureau of Standards
Subject: character recognition testing

       The National Institute of Standards and Technology (NIST)
       formerly National Bureau of Standards (NBS) has developed
       a data base for testing handprint character recognition.
       The database is on a ISO-9660 formated CD and is
       described briefly below. Please forward this to
       interested parties.


                        NIST Handprint Database

       The NIST handprinted character database consists of 2100
       pages of bilevel, black and white, image data of hand
       printed numerals and text with a total character count of
       over 1,000,000 characters. Data is compressed using CCIT
       G4 compression and decompression software is provided in
       C.
       
       The total image database, in uncompressed form, contains
       about 3 Gigabytes of image data, with 273,000 numerals
       and 707,700 alphabetic characters. The handprinting
       sample was obtained from a selection of field data
       collection staff of the Bureau of the Census, with a
       geographic sampling corresponding to the population
       density of the United States. The geographical sampling
       was done because previous national samples of 
       handprinted material have suggested that there are
       significant regional differences in handprinting style.

       Most of the individuals who participated in the sampling
       are accustomed to filling out forms relatively neatly,
       and so this sample may represent a "best possible" sample
       of handprinting.  Even so, the range of characters and
       spatial placement of those characters is broad enough to
       present very difficult challenges to the image
       recognition systems currently available or likely to be
       available in the near future.

                              Typical Use

       This test data set was designed for multiple uses in the
       area of image (character) recognition. The problem of
       computer recognition of document content from images is
       usually broken down into three operations. First the
       relevant areas containing text are located. This is
       usually referred to as field isolation. Next the entire
       field image containing one or more characters is broken
       into the images of individual characters. This process is
       usually referred to as segmentation. Finally, these
       isolated characters must be correctly interpreted. The
       images in the data base are designed to test all three
       of the processes.

       The test data can be used for any one of the three
       operations, although it is important to recognize that
       the success of all subsequent steps in this process is
       dependent on the success of the previous steps.

Subject: References to Automated Character Recognition wanted

    I would like to include some simple automated character
recognition into a system we are building.  From the little
research I have done sofar, there appears to be a rich literature
on the subject.  I would like to find out if any vision-list'ers
could point me to a "canonical" paper in the area.  I am
interested in both Printed character and handwritten character
recognition.  I am willing to consider neural net approaches
if they perform better than explicit approaches.

Please email responses and I'll summarize to the net.

Thanks,

Subject: Apparent Motion Simulator !
Organization: GTE Laboratories, Inc., Waltham, MA

I have developed a simple APPARENT MOTION simulator for the Mac just
out of my own interest in the field of Computer Vision. It simulates 
Braddick's and Koler's experiments. Possible applications/uses are : run 
experiments in apparent motion, a demonstration tool, etc. at the Psychology 
and Vision Labs of various Universities.

Technical Information : 
		        Works on Mac SE, Mac II and higher
                        Amount of Free Memory required on the system :
	                at least 2 Meg.
                        Application takes : 55K
			Source Code written in THINK C

[ Features: ]
			      It is a simple, flexible application with 
			      Macintosh "look-and-feel" alike user interface.
	                      It allows the experimenter to generate PICT
                              frames that can be stored and recalled later.

			      Constant : Number of frames that can be 
			      created and then alternated -> 2

			      Variables that are user- controlled :
			      1) Number, Size, Shape and Color of Picture 
				 Elements
			      2) Background color (from black, grey, white)
			      2) Spatial Separation Between the two frames
 			      3) Interstimulus duration and presentation
			         duration
			      4) Ability to store and retrieve picture 
				 frames
	                
Cost of the package : $20 ( manual included )

Subject: Multiplexed Codes
Organization: Boston University Center for Adaptive Systems

I'm very interested in "multiple meaning" theories (e.g. Raymond and
Lettvin, and now Optican and Richmond), the informational role that
conduction blocks in axon arbors might play, and the function of
temporally modulated pulse codes in general.  

I'm writing in order to gather references to related work.  I'm really
just getting my feet wet at this point -- I joined Steve Grossberg's
Cognitive and Neural Systems program as a PhD student in September,
and with courses and my R.A. work I've been too snowed under to really
pursue these interests very fully.

Work in temporal pulse encoding I am aware of includes

Chung, Raymond, and Lettvin (1970) Multiple meanings in single visual
	units.  Brain Behavior and Evolution 3:72-101.

Gray, Konig, Engel, and Singer (1989) Oscillatory Responses in Cat
	Visual Cortex Exhibit inter-Columnar Synchronization Which   
	Reflects Global Stimulus Properties.  Nature Vol. 338, March 
	1989.

Optican, Podell, Richmond, and Spitzer (1987) Temporal Encoding of
	Two-Dimensional Patterns by Single Units in Primate Inferior 
	Temporal Cortex. (three part series) Journal of Neurophysiology. 
	Vol 57, No 1, January 1987.

Pratt, Gill (1990) Pulse Computation.  PhD Thesis.  MIT, January, 1990.

Steve Raymond and Jerry Lettvin (1978) Aftereffects of activity in
	peripheral axons as a clue to nervous coding. In: Physiology 
	and Pathobiology of Axons. SG Waxman, ed. Raven Press, New York.

Richmond, Optican, and Gawne (1990) Neurons Use Multiple Messages
	Encoded in Temporally Modulated Spike Trains to Represent
	Pictures.  Preprint of a chapter in Seeing Contour and Color
	ed. J. Kulikowski, Pergamon Press.

... and a lot of work that has been done in the area of temporal
coding in the auditory nerve and cochlear nucleus (average localized
synchrony response (ALSR) coding).

I've finally reached a (brief) lull in my activities here, and I'd
appreciate any advice you'd care to offer.
