Embodiment Construction
[0041] The implementation process of the present invention will be described in detail below in conjunction with the accompanying drawings and specific examples.
[0042] (1) For the input image, the Canny edge detection algorithm is used for edge detection, and the edge point P of the object in the image is obtained = {p 1 ,p 2 ,...p n};
[0043] (2) Define the initial contour line according to the prior depth gradient model, and define a group of contour lines parallel to each other and with equal spacing as the initial contour line V={v 0 ,v 1 ,...,v m}. Wherein, v(s)=[x(s), y(s)], x(s), y(s) are the coordinates of the point s in the initial contour line;
[0044] The total energy of the contour is defined as
[0045] E. total =w 1 E. edge +w 2 E. sharp +w 3 E. s +w 4 E. d
[0046] where E edge is the contour edge energy function, E sharp Contour sharpness energy function, E s is the characteristic energy function of the contour line, E d is the contour...
