Adopt Roberts cross gradient operator, we get super-resolution algorithm with lower computational complexity and get better effect than bilateral total variation operator at some case. 采用Robert交叉梯度算子构造正则项,得到计算复杂度较低的超分辨率图像复原算法,而且在某些情形下其效果要比采用双边全变差算子略好。
In the paper Gradient Edge detection, Robert Edge detection and Sobel Edge detection were used to the Edge detection of the machine part. 使用梯度边缘检测算子、Robert边缘检测算子及Sobel边缘检测算子对机械零件的边缘检测的效果进行了检验。
