Target Design
Physical Targets are manufactured from materials specific to the imaging attribute being characterized. For instance, pigment-based color patches are used on Imaging Gauge™ targets to provide a known color input to the imaging system. The diagram below shows the different features of this target.
Electronic Targets are used to test output systems such as dye-sublimation, inkjet or electro-photographic printers. The printed targets are analyzed to determine how the printer affected the original image. For instance, a pure square-wave target is printed to assess the Modulation Transfer Function (MTF) of a system (including the printer media).

Synthetic targets are electronic targets that are manipulated to create test samples with known noise factors. The targets can be created from scratch or they can be based on real-life images. For instance, the original scallop images were manipulated by increasing and decreasing the brightness of the images to simulate different lighting conditions on the ship. The test algorithm was tested and modified based on these samples to increase robustness of the system.
