NIH Image is a public domain image processing and analysis program for
the Macintosh. It was developed at the Research Services Branch (RSB)
of the National Institute of Mental Health (NIMH), part of the
National Institutes of Health (NIH). It has been superseded by ImageJ,
a Java program inspired by NIH Image that runs on the Macintosh, Linux
and Windows.
Image can acquire, display, edit, enhance, analyze and animate images.
It reads and writes TIFF, PICT, PICS and MacPaint files, providing
compatibility with many other applications, including programs for
scanning, processing, editing, publishing and analyzing images. It
supports many standard image processing functions, including contrast
enhancement, density profiling, smoothing, sharpening, edge detection,
median filtering, and spatial convolution with user defined kernels.
Image can be used to measure area, mean, centroid, perimeter, etc. of
user defined regions of interest. It also performs automated particle
analysis and provides tools for measuring path lengths and angles.
Spatial calibration is supported to provide real world area and length
measurements. Density calibration can be done against radiation or
optical density standards using user specified units. Results can be
printed, exported to text files, or copied to the Clipboard.
A tool palette supports editing of color and gray scale images,
including the ability to draw lines, rectangles and text. It can flip,
rotate, invert and scale selections. It supports multiple windows and
8 levels of magnification. All editing, filtering, and measurement
functions operate at any level of magnification and are undoable.
Image directly supports Data Translation and Scion frame grabber cards
for capturing images or movie sequences using a TV camera. Acquired
images can be shading corrected and frame averaged. Other frame
grabbers are supported via plug-in modules.
Image can be customized in three ways: via a built-in Pascal-like
macro language, via externally compiled plug-in modules and on the
Pascal source code level.

Compatibility
Architecture: 68k PPC
Image requires a color capable Macintosh and at least 4MB of free RAM.
32MB or more of RAM is recommended for working with 3D images, 24-bit
color or animation sequences. Mac OS 7.0 or later is required. Image
directly supports, or is compatible with, large monitors, flatbed
scanners, film recorders, graphics tablets, PostScript laser printers,
photo typesetters and color printers.
