Pointing Hand Distinction by Improved HOG and Wavelet Multi-scale Transform
AbstractIn order to improve the accuracy of distinguish left hands and right ones from a single fixed camera, this paper proposes a new method to deal with it. The method is based on the combination of...
View ArticleNC polishing of aspheric surfaces under control of constant pressure using a...
AbstractIn this paper, a method of maintaining a constant polishing pressure is proposed for a NC polishing system by controlling the polishing force during the polishing process. First, the NC...
View ArticleVisual Objects Location Based on Hand Eye Coordination
AbstractWe present a new method to locate the objects in a plane using direction of pointing hand and facial orientation. Based on Active Shape Model, facial components such as left eye, right eye,...
View ArticleGourd pyrography art simulating based on non-photorealistic rendering
AbstractNon-photorealistic rendering (NPR) is a field in computer science which can create effective illustrations and appealing artistic imagery. Some researchers have proposed NPR methods to simulate...

AbstractBackgroundHepatocellular carcinoma (HCC) is one of the most lethal cancers worldwide owing to its high rates of metastasis and recurrence. The oncogene IQ motif-containing GTPase activating...
View ArticleComputational Investigation on Unsteady Loads of High-Speed Rigid Coaxial...
AbstractA computational fluid dynamics method is built to study the unsteady aerodynamic loads of a high-speed rigid coaxial rotor model, taking account of lift offset (LOS). The flowfield is simulated...
View ArticleA New Study on the Gap Effect of an Airfoil with Active Flap Control Based on...
AbstractRotors with active flap control have considerable potential in reducing vibration and noise and improving aerodynamic performance. However, due to the movement of the flap, there are...
View ArticleA Lichnerowicz-type estimate for Steklov eigenvalues on graphs and its rigidity
AbstractIn this paper, we obtain a Lichnerowicz-type estimate for the first positive Steklov eigenvalues on graphs and discuss its rigidity.
