Automatic multi-target recognition from two classes using quadratic correlation filters

Abstract

Correlation filters (CFs) can detect multiple targets in one scene making them well-suited for automatic target recognition (ATR) applications. Quadratic CFs (QCFs) can improve performance over linear CFs. QCFs are able to detect one class of targets and reject clutter. We present a method to increase the QCF capabilities to detect two classes of targets and reject clutter. We integrate the ATR tasks of detection, recognition, and tracking algorithms using the Multi-Frame Correlation Filter (MFCF) framework. Our simulation results demonstrate the algorithm's ability to detect multiple targets from two classes while rejecting clutter.
