Abstract

The optimum receiver for pattern recognition is designed based on multiple-alternative hypothesis testing with unknown parameters for detecting and locating a noisy or a noise-free target in scene noise that is spatially nonoverlapping with this target. The optimum receiver designed for a noise-free target has the interesting property of detecting with no error a noise-free target having unknown illumination using operations that are independent of the scene noise statistics. In this paper, we investigate the performance of the optimum receiver designed for nonoverlapping target and scene noise in terms of rotation- and scale-sensitivity of the input targets, and discrimination against similar objects. Since, in practical systems, it is not possible to have a completely noise-free target, we examine how the performance of the optimum receiver designed for a noise-free target is affected when there is some overlapping noise on the target.
