Linear cyclic voltammetry are adopted as excitation potentials to test 12 different varieties of edible oil by voltammetric electronic tongue-based structure of three electrodes. Current response signals are collected by metal electrode sensor array. Principal component analysis (PCA) algorithm is used to study the ability of distinguish of edible oil in voltammetric electronic tongue. There are differences...
In this paper, we propose a novel strategy to design a reliable and practical constant selling oil automatic system,through the use of S7-226PLC, flow meter, inverter and other hardware devices. A kind of fuzzy PID control algorithm was researched to guarantee the system accuracy. The fuzzy PID controller can control the inverter output frequency by changing the voltage of the inverter and self-tuning...
A fusion algorithm based on skin color model and optical flow is proposed to detect and track faces. It uses skin color model to detect faces and adopts optical flow algorithm to estimate the continuity of the video frames and obtain the position of faces in the frames. Taking advantages of the algorithms, the proposed method, in some degrees, gives a solution to the effects of face rotation, partial...
