Optical Differentiation and Edge Detection Based on Birefringence of Uniaxial Crystals
Optical differential operations can directly extract edge information from images and have significant application potential in fields such as image processing and object recognition. In this work, we propose an optical spatial differentiator based on the birefringence effect of uniaxial crystals. T...
