An image retrieval system is presented, which used HSV color space and wavelet transform approach for feature extraction. Firstly, we quantified the color space in non-equal intervals, then constructed one dimension feature vector and represented the color feature. Similarly, the work of texture feature extraction is obtained by using wavelet. Finally, we combine color feature and texture feature...
Gaussian mixture model (GMM) is a popular tool for density estimation. The parameters of the GMM are estimated based on maximum likelihood principle (MLP) in almost all recognition system. However, the number of mixtures used in the model is important for determining the model's effectiveness; the general problem of mixture modeling is difficult when the number of components is unknown. This paper...
Continual increases in IC-chip complexity and performance are placing demands on the density and functionality of package I/Os. Therefore, various SMT interconnection techniques are being developed to satisfy this need, including ball-grid-array (BGA). BGA has been used in a production of PCB (printed circuit board), because of their excellent characters such as high density of the lead pin pitch...
