Color Image Quantization Algorithm Based on Self-Adaptive Differential Evolution

الملخص EN

Differential evolution algorithm (DE) is one of the novel stochastic optimization methods.

It has a better performance in the problem of the color image quantization, but it is difficult to set the parameters of DE for users.

This paper proposes a color image quantization algorithm based on self-adaptive DE.

In the proposed algorithm, a self-adaptive mechanic is used to automatically adjust the parameters of DE during the evolution, and a mixed mechanic of DE and K-means is applied to strengthen the local search.

The numerical experimental results, on a set of commonly used test images, show that the proposed algorithm is a practicable quantization method and is more competitive than K-means and particle swarm algorithm (PSO) for the color image quantization.
