摘要：
The wavelet transform provides an efficient tool for signal processing. Haar wavelet is a good choice for the optical wavelet transform processor. An optical method for the production of Haar wavelet is proposed based on the grating filtering technique. The edge and corner features of an input are extracted experimentally using the Haar wavelets produced from the proposed method. (C) 2002 Elsevier Science B.V. All rights reserved.
