Roundness measurement has been a crucial issue of quality control in industry. This study proposes a roundness measuring method that applies the Particle Swarm Optimization Algorithm (PSO) for computing the maximum inscribed circle (MIC). We first conducted a design of experiment with five PSO models, in which the impact of inertia weight, maximum velocity(More)
In this paper, a hybrid approach for vector quantization (VQ) is proposed for obtaining the better codebook. It is modified and improved based on the centroid neural network adaptive resonance theory (CNN-ART) and the enhanced Linde–Buzo–Gray (LBG) approaches to obtain the optimal solution. Three modules, a neural net (NN)-based clustering, a mean shift(More)
