Resumo: A method for accelerating the fuzzy k-means algorithm is presented. A performance evaluation of the method is carried out in the scenario of vector quantization codebook design for image compression. Simulation results show that the proposed method leads to a reduction in the number of iterations performed by the fuzzy k-means algorithm. Additionally, it is shown that the convergence speed of the algorithm is increased without sacrificing the quality of the designed codebooks.
