| Abstract: |
| Based on the LBF image level set segmentation model, this paper constructed the image edge characterization function based on two-dimensional wavelet transform, which is introduced into the LBF level set segmentation variational model, the WLBF model based on wavelet transform is established and the numerical solution algorithm of the WLBF model is also given. Subsequently, the image segmentation examples is conducted on the typical gray image in different situations. According to the aspects of segmentation accuracy and efficiency,the effectiveness of WLBF model and algorithm is analyzed. |
