ImageJ

ImageJ is a scriptable Java-based image processing application for scientific analysis that can be installed free of charge on compatible computers. It allows users to display, edit, analyze, process, save, and print 8-bit, 16-bit, and 32-bit images for research and general digital work. Notably, ImageJ supports common image file formats, including TIFF, GIF, JPEG, BMP, PGM, DICOM, ASCII, FITS, and raw text-based data files. ImageJ serves as an alternative to other photography analysis tools such as Meesoft’s Image Analyzer and JPEGsnoop, offering flexibility for scientific and technical image processing tasks.
