NIH / Scion Image


NIH Image (Macintosh only)

  This is an animated gif downloaded from the NIH Image Home page. It illustrates many image processing functions available in Image.

Sample images, additional macros, source code, plug-ins, documentation, and special versions of Image are available from this page.


Scion Image (PC and Mac)

(The Mac application is the same as that available from NIH above, with additional commands for accessing the Scion imaging boards. A few images are available at this site. Most images, and macros are available at the NIH site.)


Image/J ( Image / Java ... PC, Mac, Linux, ... )

NIH Image and Scion Image are now static. Image/J is where the development is taking place.

Image/J now has all of the image processing functions of NIH Image/ Scion Image , and supports more types of images: 8-bit grayscale, 8-bit indexed color, 16-bit signed integer, 32-bit floating-point and 32-bit RGB color.

Processing commands now often work on color as well as gray scale images. Process -> Sharpen, for example works on a RGB color image in IMAGEJ.

A gamma adjustment is available: Process -> Math -> Gamma... which was not available in NIH Image.

Image/J runs as a standalone application on both the Mac and PC. The interface has some differences from the NIH/Scion image, for example the threshold function is now under Image -> Adjust -> Threshold, rather than in the vertical slider bar that is always visible in NIH Image.. The ImageJ interface is almost identical between the PC and the Mac.

Image/J can be run over the network on a set of demonstration images.

I recommend downloading it and running it locally.

Version 1.32 of Image/J has many of the menus in NIH Image. Image/J supports more types of images: 8-bit grayscale, 8-bit indexed color, 16-bit signed integer, 32-bit floating-point and 32-bit RGB color. See http://rsb.info.nih.gov/ij/features.html for other features, especially the list of planned features at the bottom, many of which are included in v1.32.
