Figure 4

This image is taken from the Berkeley’s data set\(^1\). First row shows the given image and the zero level set initialization, the second row shows the segmentation contour and the last row denotes the binary image resulting from the reconstruction of each method involved in the comparison. First, second, third and fourth columns are the segmentation results of Wu et al.²⁴, Li et al.¹⁵, Wu et al.¹² and Krinidis et al.³¹, respectively. The fifth column illustrates the result of proposed model with \(p=0.5\), \(\mu \)=0.7, \(\sigma \)=3, with speckle noise = 0.2.
