Extracting hand articulations from monocular depth images using curvature scale space descriptors
Shao-fan WANG,Chun LI,De-hui KONG,Bao-cai YIN
Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 1, Pages 41-54 doi: 10.1631/FITEE.1500126
We propose a framework of hand articulation detection from a monocular depth image using curvaturescale space (CSS) descriptors., and obtain the fingertips and finger-valleys of the contour using the local extrema of a modified CSStraditional appearance-based approaches using either angle detectors or convex hull detectors, the modified CSS

Waves of Probability and the Problems of Torsion for Quantum Effect
OuYang Shoucheng,Li Zhilan,Yuan Dongsheng
Strategic Study of CAE 2005, Volume 7, Issue 6, Pages 1-6
In this paper, the numerical experiment is conducted for Schrödinger's equivalent equation with third order derivative for nonlinear variable. The results show that the probability of probability waves is the quasi-regular flow under given condition, and it's a result of comprehensive interactions among intensity of potential field and particle density and torsion (spin) field with the quantum effect. The pure quantum effect is represented only by irregular flow.
