| Abstract: | In this paper,based on theoretical and experimental study of Canny`s optimal edge detection operator,we analyze the advantages and shortage of Gauss and spline filter,causes of missing slow changing edge,and new improved algorithm is proposed in which Gauss filter is replaced by spline filter and which reduces slow changing edge missing.Experiment shows that improved algorithm has higher SNR and a much better edge detection result. |
