ImageJ

ImageJ Publisher'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 this version:

* Converted the FluorescentCells sample image into a three channel composite color image.
* The Image Calculator now creates a hyperstack when the input is a hyperstack.
* Fixed a bug that could cause macros (not in batch mode) running the particle anlyzer on a stack to not run reliably.
* Fixed a bug that caused reading of LZW compressed TIFF stacks to fail.
* Fixed a bug that caused the LSM Reader to not correctly open LSM files using LZW compression with differencing.
* Fixed a bug that caused Image>Color>RGB Merge, when creating a composite image, to sometimes not use expected the channel colors.
