There is an enhanced version of ImageJ called FIJI?

ImageJ is a free and very capable image analysis software made available from the National Institutes of Health (NIH). The software was written by Wayne Rasband, who retired from the NIH in 2010, but continues to support the software. ImageJ is written in Java, which allows it to run on Linux, Mac OS X and Windows, in both 32-bit and 64-bit modes.

As good as ImageJ is, we strongly encourage users to use FIJI instead. FIJI is a free, enhanced version of ImageJ2 that includes many pre-installed macros, including the Bio-Formats plugin. Bio-Formats allows FIJI to open the majority of the proprietary file formats that microscope vendors use to store images. FIJI also has a built-in macro that keeps the software up-to-date.
