概要
- 論文の詳細を見る
Real-time rotational invariant pattern recognition is demonstrated using the method of circular harmonic filtering (CHF) in a photorefractive crystal such a BaTiO_3 to perform pattern recognition via four-wave mixing (FWM). Experimental results have shown that the recognition result is fully rotational and shift invariant.
