In EMG hand movement recognition, the first and the most important step is feature extraction. The optimal feature is important for the achievement in EMG analysis and control. In this paper, we present a statistical criterion method using the ratio between Euclidean distance and standard deviation, which can response the distance between two scatter groups and directly address the variation of feature...
We present a novel design of a quadratic filter (QF) in order to improve the quality of contrast-assisted ultrasound images for medical diagnosis. The design of QFs for capturing the second order nonlinearities is performed in frequency domain. The two-dimensional (2D) frequency response of the optimum quadratic filter is composed of two 2D Gaussian functions with different spreads in their major...
