Figure 2From: Image segmentation algorithm by piecewise smooth approximationResults of the RSF and LIF models for a vessel image with five distinct initial contour sizes and shapes. Upper row: original image and initial contours. Middle row: segmentation results of the RSF model (2000, 350, 2000, 2000, 2000 iterations). Lower row: segmentation results of the LIF model (2000, 500, 200, 500, 2000 iterations).Back to article page
