Contrast sensitivity is the ability of an imaging process to produce an image of objects or tissues in the body that have relatively small physical differences or inherent contrast. The contrast that is to be imaged is in the form of some specific physical characteristic.
Here the criterion for realism is that the image has to provide the. same visual stimulation as the scene. If we neglect optical filtering and scattering in the eye, this means that the image. has to be an accurate point-by-point representation of the spectral irradiance values at a particular viewpoint in the. scene.
