Use of rejection class to enhance airborne imagery classification

The performance of a prior classification work is enhanced by introducing a rejection class that accurately describes a particular source of false alarm. Success of this enhancement is measured by observing changes in the receiver operating characteristic (ROC) curves corresponding to two different fixed strengths of the rejection class. Source data is taken from airborne imagery collected by a line-scanner system known as REMIDS (Remote Identification System) through funding from the Environmental Security Technology Certification Program (ESTCP).
