| Abstract: | A Zernike moment based edge
detection method is presented. An edge model with four parameters has been built. The relations
between edge parameters and Zernike moment are derived form Zernike moment character. The
value of edge parameters is calculated to get the edge image. This method can detect subpixel
level edges, being insensitive to noise and presenting robust performance. |

| Keywords: | edge detection Zernike moment subpixel level |
