[0028] The train of thought of the present invention is: the mimic physics optimization algorithm is a kind of new group random search algorithm, has better global search ability, is difficult to fall into the local optimum, the characteristics of stability and fast convergence and better robustness, and It has been successfully applied in single and multi-objective optimization problems. Therefore, the present invention applies it to the hyperspectral image band selection method.
[0029] The method of the present invention comprises the following steps: 1, setting of motion space; 2, initialization; 3, calculating the fitness value of the initial population; 4, calculating the resultant force of the individual in the population; 5, updating the speed and position of the individual; 6, Calculate the fitness value of the updated population individual; 7. Iterative calculation, repeat steps 4-7 until the maximum evolutionary generation is reached; 8. Output the optimal band com...
