This paper presents an improved genetic algorithm for the optimization of the structure element used in morphological open and closed filtering. Considering that the evaluation of the froth images of coal flotation is categorized as a no-reference image evaluation, in the optimization of the structural element, a denoising evaluation index of an improved information capacity was used as the adaptation degree function. In addition, this paper proposes the determination method of chromosome length in the structure element optimization algorithm. In the improved genetic algorithm, based on adaptive variation, the variation regulation factor and the mechanism of concentration adjustment are introduced. When compared to an optimization process of the structural element in froth image denoising using the genetic algorithm, the adaptive genetic algorithm, the improved genetic algorithm improves the efficiency and accuracy of the optimization process. It has been proven that optimizing the structural element by the improved genetic algorithm increases fitness and reduces noise when using morphological open and closed reconstruction filters.

Background: In order to make up for the shortcomings of the traditional algorithm, Min-Min and Max-Min algorithm are combined on the basis of the traditional genetic algorithm. Methods: In this paper, a new cloud computing task scheduling algorithm is proposed, which introduces Min-Min and Max-Min algorithm to generate initialization population, and selects task completion time and load balancing as double fitness functions, which improves the quality of initialization population, algorithm search ability and convergence speed. Results: The simulation results show that the algorithm is superior to the traditional genetic algorithm and is an effective cloud computing task scheduling algorithm. Conclusion: Finally, this paper proposes the possibility of the fusion of the two quadratively improved algorithms and completes the preliminary fusion of the algorithm, but the simulation results of the new algorithm are not ideal and need to be further studied.
