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 Thomas Boudier, added five new 3D filters (Median, Mean, Minimum, Maximum and Variance) to the Process>Filters submenu.
- Added the “Restore Startup Tools” command to the toolbar’s >> menu.
- Thanks to Tiago Ferreira, built-in and plugin tools can be added to toolsets and the startup macros (example).
- Michael Schmid modified the Overlay Brush tool for constrained motion (vertical or horizontal) with shift and resizing with ctrl-shift (cmd-shift on Mac… See all new features
