Embodiment Construction
[0094] The method of the present invention will be further described below in conjunction with the accompanying drawings.
[0095] Step (1). Liver cancer images and their corresponding pathological classification labels are used as training data sets;
[0096] Step (2). Using the GrowCut algorithm to achieve semi-automatic segmentation of the liver cancer lesion area. in grid position (pixels or voxels in image processing). The cellular automaton is expressed as a triple A=(S,N,δ), where A represents a cellular automaton model, S is a non-empty state set, N is the domain system, δ:S N → S is the local transition function, which defines the rules for computing the state of a cell at t+1 time steps given the state of a neighborhood cell at time step t. The neighborhood system N used is the von Neumann neighborhood:
[0097]
[0098] cell state where l p Indicates the label of the current cell, θ p is the current cell strength, is the feature vector of the current c...
