Tools and Data
ImageJ is a public domain Java image processing program. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.1 or later virtual machine. ImageJ 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 and JPEG. It can "stack" a series of images that share a single window. It can calculate area and pixel value statistics of user-defined selections. It can measure distances and angles. Images can be zoomed up to 32:1 and down to 1:32. All analysis and processing functions are available at any magnification factor. Spatial calibration can be set to provide real world dimensional measurements.
