To improve the retrieval rate of contourlet transform texture image retrieval system, a new texture image retrieval system was proposed. In the system, contourlet-S, which was a combination of non-subsampled Laplacian Pyramid and critical subsampled directional filter banks, was used to extract directional information of different scales. Generalized Gaussian Density (GGD) model parameters were cascaded...
Aiming at improving the retrieval rate of the original contour let transform based texture image retrieval system, a non-sub sampled contour let transform based texture image retrieval system was proposed. Generalized Gaussian Density (GGD) model parameters were cascaded to form feature vectors and Kullback-Leibler distance (KLD) function was used for similarity measure. Experimental results on 640...
Motor prognosis has great benefit for motion control systems. It is desirable to develop the so-called integrated prognosis capability for motion control products, i.e. with only the existing sensors of a motor drive. This paper presents a scheme of integrated wear prognosis for linear actuators driven by AC servo motor with only current measurement. The hidden semi-Markov model (HSMM) was adopted...
