In order to reduce the number of accidents caused by the call when the driver was driving, this paper uses the computer vision technology to dectet the behavior of the driver. Based on the constrained local models (CLM) to detect the characteristic changes of the mouth area, combine the HSV color space and the template matching to detect the hand characteristics to judge whether the driver has the...
The facial feature points localization is the core of face recognition, and its accuracy directly affects the accuracy of face recognition system. The accuracy of facial feature points is affected by light, noise, background, and face gestures. Considering the theoretical value and practical significance of facial feature points localization, this thesis goes into the most advanced algorithm of facial...
In this paper, the face modeling problem, a random forest model on each feature point by pixel difference feature, by regression estimation of forest model shape training samples; to estimate the shape of training samples for linear least squares fitting and real shape, a global optimization model; and then use the model to test the sample feature point location regression estimation and shape optimization,...
This paper focuses on the problem of stability analysis and control synthesis for nonlinear systems with variable sampling based on Takagi-Sugeno(T-S) fuzzy model approach. A novel piecewise Lyapunov-Krasovskii functional is constructed for stability analysis and controller design. Based on the feasibility of a set of linear matrix inequalities (LMIs), the sufficient conditions of stabilization via...
