Abstract

The position of sensor elements of an imaging sensor relative to the image is usually not well defined. It has some arbitrary value and changes due to movements of sensor and object. The discrete local sampling usually prevents to exactly hit a sharp maximum in the image and thus will as a rule underestimate data for maximum intensity taken automatically from images. Such variations of intensity data on relative position of a sensor will be treated here as a specific noise type: position noise.
