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:
- Fixed a bug that caused ImageJ to incorrectly read 3 and 4 channel 16-bit planar TIFFs.
- Thanks to Dawid Krzempek and Michael Schmid, fixed bugs that caused the setFunction() and setCTable() methods of the Calibration class to sometimes not work as expected.
- Thanks to Rodrigo Goncalves, fixed a bug that caused the size of maximized windows to be reset when they were moved on Windows 7 and Windows 8.
- Fixed a 1.49k regression that could cause the imageCalculator() m... See all new features »
