Postdoctoral Positions
Send submissions, questions, address maintenance, and requests for old
issues to "neuron-request@cattell.psych.upenn.edu". The ftp archives are
available from cattell.psych.upenn.edu (128.91.2.173). Back issues
requested by mail will eventually be sent, but may take a while.

Binary Images of Handwritten Segmented Characters
(HWSC)
The NIST database of handwritten segmented characters contains 313,389
isolated character images segmented from the 2,100 full-page images
distributed with "NIST Special Database 1". The database includes the
2,100 pages of binary, black and white, images of hand-printed numerals
and text. This significant new database contains 223,125 digits, 44,951
upper-case, and 45,313 lower-case character images. Each character image
has been centered in a separate 128 by 128 pixel region and has been
assigned a classification which has been manually corrected so that the
error rate of the segmentation and assigned classification is less than
0.1%. The uncompressed database totals approximately 2.75 gigabytes of
image data and includes image format documentation and example software.
"NIST Special Database 3" has the following features:
+ 313,389 isolated character images including classifications
+ 223,125 digits, 44,951 upper-case, and 45,313 lower-case images
+ 2,100 full-page images
+ 12 pixel per millimeter resolution
+ image format documentation and example software
Suitable for automated hand-print recognition research, the database
can be used for:
+ algorithm development
+ system training and testing
The database is a valuable tool for training recognition systems on a
large statistical sample of hand-printed characters. The system
requirements are a 5.25" CD-ROM drive with software to read ISO-9660
format.

8-Bit Gray Scale Images of Fingerprint Image Groups
(FIGS)
The NIST database of fingerprint images contains 2000 8-bit gray scale
fingerprint image pairs. Each image is 512 by 512 pixels with 32 rows of
white space at the bottom and classified using one of the five following
classes: A=Arch, L=Left Loop, R=Right Loop, T=Tented Arch, W=Whirl. The
database is evenly distributed over each of the five classifications with
400 fingerprint pairs from each class. The images are compressed using a
modified JPEG lossless compression algorithm and require approximately
636 Megabytes of storage compressed and 1.1 Gigabytes uncompressed (1.6 :
1 compression ratio). The database also includes format documentation and
example software.
"NIST Special Database 4" has the following features:
o 2000 8-bit gray scale fingerprint image pairs including
classifications
o 400 fingerprint pairs from each of the five classifications Arch,
Left and Right Loops, Tented Arch, Whirl
o each of the fingerprint pairs are two completely different
rollings of the same fingerprint
o 19.6850 pixels per millimeter resolution
o image format documentation and example software
Suitable for automated fingerprint classification research, the database
can be used for:
o algorithm development
o system training and testing
The database is a valuable tool for evaluating fingerprint systems on a
statistical sample of fingerprints which is evenly distributed over the
five major classifications. The system requirements are a 5.25" CD-ROM
drive with software to read ISO-9660 format.

Structured Forms Reference Set
(SFRS)
The NIST database of structured forms contains 5,590 full page images of
simulated tax forms completed using machine print. THERE IS NO REAL TAX
DATA IN THIS DATABASE. The structured forms used in this database are 12
different forms from the 1988, IRS 1040 Package X. These include Forms
1040, 2106, 2441, 4562, and 6251 together with Schedules A, B, C, D, E, F
and SE. Eight of these forms contain two pages or form faces making a
total of 20 form faces represented in the database.
Each image is stored in bi-level black and white raster format. The
images in this database appear to be real forms prepared by individuals
but the images have been automatically derived and synthesized using a
computer and contain no "real" tax data. The entry field values on the
forms have been automatically generated by a computer in order to make
the data available without the danger of distributing privileged tax
information.
In addition to the images the database includes 5,590 answer files, one
for each image. Each answer file contains an ASCII representation of the
data found in the entry fields on the corresponding image. Image format
documentation and example software are also provided.
The uncompressed database totals approximately 5.9 gigabytes of data.
"NIST Special Database 2" has the following features:
+ 5,590 full-page images
+ 5,590 answer files
+ 12 pixel per millimeter resolution
+ image format documentation and example software
Suitable for automated document processing system research and
development, the database can be used for:
+ algorithm development
+ system training and testing
The system requirements are a 5.25" CD-ROM drive with software to read
ISO-9660 format.

On the question of code generation from a modelled neural network:
NeuralWare in Pittsburgh, PA has NeuralWorks Professional II+ which can
model a number of neural networks and generate C code.
I do not have a financial interest in NeuralWare but I do, when they ask,
provide them with objective comments on their product line.
