GSA Image Analyser is imaging software used to analyze 2D images with the ability to detect and count objects, as well as calculate distance areas. Importing images from various sources (file, scanner, microscope, cam) is supported.

The software is designed with a set of functions specifically crafted to enable direct length calculations of intricate, ramified objects like plant roots. Moreover, it also offers an indirect calculation feature utilizing grid intersections (developed by Tennant), and for this feature, users can freely define the grid size. The automatic count feature enables the program to determine the number of recognized objects, and it allows counting overlapping objects separately, based on the object's form, surface, or intensity.
In addition to the automatic count functions, the software comes with two manual counting procedures, one of which marks the objects inside the image, whereas the other cuts the image into smaller pieces, simplifying the counting process. The GSA Image Analyser can read almost all known picture formats, including JEPEG, GIF, TIFF, BMP, and PNG, and it provides interfaces to microscopes, scanners, and digital cameras (TWAIN) as well as video cameras (Video grabber, TV cams).
The software is incredibly diverse and can be used for numerous applications. The program can count cells, calculate the size of plant roots, and solve other biometric problems. Overall, the GSA Image Analyser is an invaluable tool for scientific image analysis.
