Intelligent Scissors algorithm
4.0
Application background The basic idea is to divide the image as a connected graph. The pixels in the image are used as the nodes in the graph, and the edges between the adjacent pixels are as the edges of the connecting nodes. On every side define a cost function, as strong edges is assigned a smaller value, non strong edge given a larger value, also between adjacent pixels arc Fu 0 cost, rather than between adjacent pixels arc Fu + infinity price, will split transformation as the starting point to the target point between the optimal path problem. Then the boundary of the object is searched through the graph search, and the shortest path between two points on the object boundary is treated as the boundary of the object. Key Technology Algorithm procedures by the mouse click, click the left mouse button set as the starting point, the mobile mouse, the program automatically outline the outline, to find a satisfactory contour, click the left mouse
