在矢量Ｐｒｅｗ ｉｔｔ算子的基础上，引入多尺度组合正则化处理，提出了一种新的彩色图象边缘检测方法。实验表明，若对检测精度、边缘完整性、抗噪性等方面进行综合评价，该方法优于标量算子和单一尺度下的矢量算子
Based on vector Prewitt operator, multi-scale combination regularization is introduced and a new color image edge detection method is proposed. Experiments show that the proposed method is superior to scalar operators and vector operators at a single scale in the aspects of accuracy, edge integrity and noise immunity.
