Algorithm 2: PFCM Pseudo-Code
|
Let the vectors of voxels, the matrix of membership degrees, the matrix of typicality degrees, the matrix of cluster centers with
m the degree of fuzzy and the degree of weight possibilistic.
Initialize the centers vectors B(0) = [bj] and the degrees of belonging matrix U(0) using hybrid BCFCM-GA method.
At k-step:
-
-
Compute the matrix of membership degrees U(k) using Equation (9).
-
-
Compute the matrix of typicality degrees T(k) using Equation (10).
-
-
Compute the prototype matrix B(k) using Equation (11).
-
-
Compute the objective function using Equation (8).
Update: U(k+1), T(k+1), B(k+1) and
Repeat steps (2) and (3) until the stop criterion is met:
