New optoelectronic morphological scheme for multiple-object recognition
Zhongbing Yao · Optical Engineering · 1994
Based on the binary image algebra algorithm for a hit-or-miss transform of mathematical morphology, a new optoelectronic system with two parallel channels is set up for real-time multiple-object recognition. Two Dammann gratings are used for convolutions in morphological operations. The relation of rotation-recognizing sensitivity to the threshold values is discussed.
