Image Analysis Software

NIH Image

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). A free PC version of Image, called Scion Image for Windows, is available from Scion Corporation. There is also Image/J, a Java program inspired by Image that "runs anywhere".
