Abstract

Many problems in pattern recognition require the identification of an object that has an unknown rotational orientation, and many rotationally invariant correlation techniques have been proposed.¹ This paper describes two rotational-invariant methods utilizing a joint transform correlator that can be implemented with liquid crystal televisions (LCTVs).²
