Nutritional and organoleptic qualities (taste, smell, texture, appearance) are key characteristics of seafood when it comes to defining consumer choices. These qualities, which are determined by the biochemical properties of the seafood, can be alter

In our previous paper we proposed using successively binary cosine and sine filters and combining the correlation intensities for rotation-invariant phase-only circular harmonic correlation. This paper presents an alternative method that uses a singl

Phase-only circular harmonic filters and binary phase-only circular harmonic filters are proposed. Both filters have full rotation invariance and excellent performance for discrimination between objects and against background noise. Their properties

We propose using the covariance function as a measure of similarity in the circular harmonic matched filters for rotation invariant pattern recognition and for discrimination against unwanted objects which are unknown a priori. An optical covariance

We present some theoretical considerations on the appearance of sidelobes in the pattern recognition process when use is made of the composite filter of Caulfield and Maloney. The results previously obtained in this field by us and other workers are

We review recent work on rotation invariant pattern recognition. We briefly review results involving Circular harmonic filters, then describe some of our more recent research in this area. A pattern classification system that achieves rotation invari

Four different thin DOE pattern generation techniques used at National Optics Institute (NOI) are discussed and compared: laser direct writing in photoresist, microlithography with e-beam masks, holographic recording, and laser assisted microfabricat

A rotation invariant optical correlator using a low-cost, liquid crystal television (LCTV) in the Fourier plane is described. The performance of the LCTV used as a filter support medium is evaluated, using interferometric measurements and an image re

This paper reviews recent progress in rotation invariant pattern recognition; the emphasis is on the work done in our own laboratories, since much of the significant work done elsewhere is described in other papers presented at this conference.
