Shape Prior Embedded Level Set Model for Image Segmentation

Algorithm 1

Shape prior embedded LSM.
I.Initialize the LSF as a simple numerical function according to equation (18)
II.Set related control and attribute parameters, including , , , , , , , , and
III.Update the value of according to equation (14)
IV.Iteratively update the values of and according to equations (3) and (6), respectively
V.Generate the value of according to equation (11), where the single shape prior and multiple shape priors need to be considered separately
VI.Update the LSF according to equation (10)
VII.Repeat the operations shown in steps III to VI until the evolution process reaches the state of convergence
