| Abstract: | The superiority of wavelet transform in image edge extracting is presented in the paper in detail.Based on many references,a wavelet function often used in edge extracting,its method and effects are sum up.A conclusion that the first derivative of Gaussian function used in the image edge extracting is an effective wavelet function in commom use is obtained.The computer simulation results obtained by extracting the static object edge with the first derivative of Gaussian function are given in the end. |
