|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.
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 , 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 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 supports more types of images than NIH Image: 8-bit grayscale, 8-bit indexed color, 16-bit signed integer, 32-bit floating-point and 32-bit RGB color.
