From: Variational segmentation model for images with intensity inhomogeneity and Poisson noise
Segmentation results of the proposed and RSF models on four real radiograph images. First row (a-d), the original images with the initial contours. Second row (e-h), results of the RSF model (from left to right, the regularization parameters are v = 0.003 × 2552, v = 0.0045 × 2552, v = 0.004 × 2552, and v = 0.004 × 2552, respectively). Third row (i-l), results of the proposed model. Fourth row (m-p), final level set functions of the proposed model for the corresponding image.
