This paper develops band weighting spectral methods, which are wSAM and wSID, for detection of pesticide residues on vegetables. Since the water content of vegetables has significant impact on the measured spectrum, the propsoed band weighting measures are able to suppress the effect of water content to enhace detectability of of pesticide residue detection. Compared to the traditional band selection...
This paper presents a virtual touchpad for smartphone with depth camera such as HTC One(M8). Hand gesture recognition is used as a new human machine interface for hand-held devices. This system consists of three modules: (1) open hand extraction, (2) active fingertip detection and tracking, and (3) hand gesture recognition. In the experiment, we show that our method can detect the active fingertips...
A method to determine the norm vacuum of duplex pressure condenser based on the support vector regression (SVR) model was proposed, The norm vacuum of condenser is usually obtained from the characteristic curve given by the manufactory. But the method is only fit for the condition that both of the flow of cooling water and exhaust steam of steam turbine are maintained at designed valves. In this paper,...
