Developer's Description

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 version 1.53e

  • Thanks to Wei Ouyang, ImageJ now runs in web browsers (Chrome or Firefox). Thanks to Michael Schmid, the color picker tool has a new icon and a right click drop down menu. The "Black background" option is no longer saved in the preferences file. Add setOption("BlackBackground",true) to Edit>Options>Startup to have it set 'true' on startup.
  • Thanks to Kees Straatman, improved recording of the Edit>Selection>Add to Manager command.
  • Thanks to Michael Ellis, added a module-info.java file, used by the Java Module System, to the ImageJ source.
  • Thanks to 'mkhapp', added the RoiManager.selected macro function, which returns the number of selected ROIs in the ROI Manager (example).
  • Thanks to Fred Damen, added the ImagePlus.copyToSystem() method.
  • Thanks to Philippe Carl, fixed a bug that allowed multiple copies of the Color Picker to be opened.
