Quantum Image Edge Detection Based on Multi-Directions Gray-Scale Morphology.

Aiming at extending the classical strong mathematical morphology operations to quantum image processing field, in this paper, an quantum image edge detection method is designed based on the novel enhanced quantum representation of digital images (NEQR) and multi-directions Gray-scale morphology. Because NEQR is more convenient for gray operation of quantum image. In addition, based on multi-directional feature of image edges, the multi-directional structures are constructed by combining the mathematical morphology. Compared with the existing quantum image edge detection methods, this method can reach a better effect. [ABSTRACT FROM AUTHOR]
