Abstract: This paper puts forward a novel algorithm of edge detection based on Green function.And the exact differential operator is obtained after detail mathematic deducing and calculation.It is approved that this algorithm has the character of simpleness and efficiency.The solution of experimentation is better than that of Canny’s algorithm after compared with others operators.

Key words: Green function, edge detection, differential operator, image processing

摘要: 提出了一种基于格林函数的边缘提取新算法,而且经过详细的数学推导与计算,得到算子的精确解析式。通过实验结果发现该算子计算简单、有效,与其他算子作用效果相比较发现其效果较Canny算法要好。
