as an introduction to digital image enhancement. The list represents only a
small sampling of the wide assortment of products available. The first group
(Public Domain), although not primarily designed for forensic identification
purposes, can prove very useful. Experiment and enjoy!
Image processing and analysis program
for Microsoft Windows 95, 98 or Windows NT.
Can read and write over 22 common
file formats including BMP, PCX, TIF, GIF and JPEG.
Image analysis functions include
dimensional (distance, angle, perimeter, area) and gray scale
measurements (point, line and area histogram with statistics).
Supports standard image processing
functions such as contrast manipulation, sharpening, smoothing, edge
detection, median filtering and spatial convolutions with user-defined
convolution masks.
Software program for the capture and
enhancement of latent fingerprints
Features such as contrast
enhancement, digital filtering, image scale, zoom & rotate. In
addition, Latent Pro II contains many functions that are unique to
forensic imaging. Some of these functions include a FFT interface, the
ability to add, remove or modify "marks" on the latent print
as well as "tracing" of the latent

Digital Technology.
Considered by many to be the leader
in Image Processing and Analysis Software.
Uses equalization, background
subtraction, correction, and field flattening methods to enhance images.
Filtering functions will sharpen, soften, blur, or enhance edges.
Separate touching or overlapping objects
Execute complex image manipulations
that are possible only in the frequency domain with high-speed Fast
Fourier Transform (FFT) operations
