Image matching based on optical XOR logic operation
HE An-zhi · Acta Optica Sinica · 1993
A new approach of image matching based on optical logic operation is proposed. The best match is indicated by the minimum collected transmitted light intensity resulted from optical XOR logic operations between the input image and every stored image. Polarization coding and multi- imaging technique are employed in our optoelectronic system. Experimental results are presented.
