ImageJ
Scriptable Java app for scientific image processing
ImageJ is a Java based application for analyzing images.
ImageJ runs either as an online applet or as a downloadable application which you'll find here. ImageJ can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images and supports most major formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and "raw".
The main use of ImageJ is that it can calculate area and pixel values which may be useful for graphic designers. It does however go a little beyond that too, allowing you to measure distances and angles, create density histograms and also line profile plots. It supports other standard image processing functions too such as contrast manipulation, sharpening, smoothing, edge detection and median filtering.
Although ImageJ can be a bit slow in Java, its a decent image analysis tool considering its completely free.
Recent changes
- Added the Image>Stacks>Tools>Remove Slice Labels command.
- The Process>Batch>Convert command averages when downsizing.
- Thanks to Michael Doube, fixed a bug that could cause an exceptionwhen the image window was closed while a stack was being saved in TIFF format.
- Thanks to Valerio Mussi, fixed bugs that caused the ROI Manager to notwork as expected when the image origin was not at the top left corner.
- Thanks to Tomas Karlsson, fixed a bug that sometimes caused the "+" and "-"keyboard shortcuts (zoom in/zoom out) to not work as expected with non-US keyboards.
- Fixed bugs that caused run() macro calls with options like "open=&dir", "size=&min-&max"and "range=&first-&last" to fail.
- Fixed a 1.45j regression that caused the RankFilters.rank() method to fail.
- Works across platforms
- Free to use
- Measures pixels, draws histograms and more
- Can be slow and unresponsive because of Java

awesome. old fellows don't understand how it works. not user friendly. however, if you have a good teacher and install the necessary plugins, you are unbeatable. you will love it for the job it does for you
- ability to process stacks and timecourse data
- the wide variety of plugins
- sometimes i selected an ROI in one slice and then save the file as TIFF, when i open the file later, the selection stay as a part of the image. i jsut can't get rid of that. makes it unusable for later use in creating presentations
- i wish there was a tool that would allow me to create a macro without having the knowledge of java. it wouldn't be that hard to make. as example, i need to create a macro that will do some functions sequentially. like i have opened a timecourse. there is drift along x and y axes. the background fluorescence increases with time. so i need to move each slice a certain distance along the axes, calculate the background intensity, deduct each slice's background from the field average and plot a z-axis profile of the timecourse for the selected region. one click, to start the whole sequence. the tool may allow me to add 10 or 20 functions of my choice from the menu and customize the values for each. i will add the functions to this empty fields one by one
