摘　　要：在二值旋转形态算子研究的基础上,研究了基于旋转变换的灰值形态算子的相关理论及方法,通过引入本影集合上的点积运算和灰值旋转变换等方法,将本影变换与表面算子应用于构建灰值旋转形态算子,提出并建立了基于空间旋转变换的灰值腐蚀、膨胀及开、闭算子,论证了一系列重要的性质,这些结论充实了基于旋转变换的形态学理论.Based on the binary rotation morphological operators, the research on related theory and method of the gray-value morphological operator with rotation transform was proposed.By introducing the dot product operation of the umbra set and gray-value rotation transform for gray-value images, umbra transform and surface operator were applied to build gray-value rotation morphological transform, including erosion, dilation, opening and closing operator.The main structures and properties were considered, and the methods for solving them within the framework of rotation morphological operator were described,some important properties were obtained and they enriched the rotation morphology.
