ImageJ is a public domain Java image processing program inspired by NIH Image for the Macintosh. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.1 or later virtual machine. It can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. It can read many image formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and "raw". It supports "stacks", a series of images that share a single window. It is multithreaded, so time-consuming operations such as image file reading can be performed in parallel with other operations. It can calculate area and pixel value statistics of user-defined selections. It can measure distances and angles. It can create density histograms and line profile plots. It supports standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection and median filtering. It does geometric transformations such as scaling, rotation and flips. Image can be zoomed up to 32:1 and down to 1:32. All analysis and processing functions are available at any magnification factor. The program supports any number of windows (images) simultaneously, limited only by available memory. Spatial calibration is available to provide real world dimensional measurements in units such as millimeters. Density or gray scale calibration is also available.
What's new in this version:
- Thanks to John Brear, the particle analyzer now allows particles to
be selected on circularity values greater than 1.0.
- Thanks to Johan Doornenbal, the Image>Scale command works
when Width or Height are not given.
- Thanks to Mirekslouf, labeling of point selections in overlays now
reflects the state of the "Label points" checkbox in the "Point Tool" dialog.
- Thanks to Bastian Schmidt, added code to the DICOM importer to handle tags of
type SS (signed 16-bit...
