Variational Level Set Method for Two-Stage Image Segmentation Based on Morphological Gradients

Figure 2

Segmentation results by both models: the proposed model and RSF model on the synthetic image with different noise. First row: original image and noisy images (Gaussian white noise with zero mean with different variances: 0.02, 0.1, and 0.2 for (b)–(d)); second row: the proposed model; third row: RSF model.
