Abstract - In this paper we present two methods for non-uniformity correction
of imaging array detectors based on neural networks, both of them exploit image
properties to supply lack of calibrations while maximizing the entropy of the
output. The first method uses a self-organizing net that produces a linear
correction of the raw data with coefficients that adapt continuously. The
second method employs a kind of contrast equalization curve to match pixel
distributions. Our work originates from Silicon detectors but the treatment is
general enough to be applicable to many kinds of array detectors like those
used in Infrared imaging or in high energy physics.
