Traffic classification is currently a significant challenge for network monitoring and management. Feature selection is an effective method to realize dimension reduction and decrease redundant information. To realize accurate traffic classification at lower price of evaluations, a hybrid feature subset selection method is proposed on the base of sliding block, the size of which is flexible according...
An image segmentation approach based on independent component analysis and watershed algorithm is proposed to complement medical image segmentation efficiently. Considering that the noise, uniform gray intensity and many low contrast adjacent areas in the medical images may cause the images over-segmented when using the watershed algorithm, so that the independent component algorithm is applied to...
Traditional watershed segmentation is sensitive to noise and can leads to serious over-segmentation. In order to overcome the shortcomings of traditional watershed segmentation, this paper presented an improved watershed image segmentation method. Firstly, the morphological opening/closing reconstruction filter is applied to remove the image noise. Secondly, multi-scale structure elements are used...
