[0020] refer to figure 1 , the specific implementation steps of the present invention are as follows:
[0021] Step 1. Use the level set method to detect the target contour on the input image, and obtain the initial target and background binary segmentation results;
[0022] 1.1) Select any area R in the input image I as the initial target area, and the area I-R outside the initial target area is the initial background area, and obtain the initial level set function φ 0 :
[0023] φ 0 ( x , y ) = - c , ( x , y ) ∈ R c ...
