Abstract: |
In this paper, we study the problem of image segmentation based on level set. By using wavelet transform method, the image edge characterization function is constructed and 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. For typical grayscale images under different scenarios, examples of image segmentation are given, and the LBF model and algorithm are generalized, experimental results demonstrate the effectiveness of WLBF for image segmentation. |
