The objectives of the present study are the formulation of the models of flame front evolution capturing the effects of flame propagation in the prescribed non-stationary premixed gas flow field. The algorithm of real time simulations of flame evolution within frame of “flamelet” approach is offered to model shape of flame front propagating in the given non stationary gas flow fields. The algor...

Abstract. In this paper, we present a shock capturing discontinuous Galerkin (SC-DG) method for nonlinear systems of conservation laws in several space dimensions and analyze its stability and convergence. The scheme is realized as a space-time formulation in terms of entropy variables using an entropy stable numerical flux. While being similar to the method proposed in [14], our approach is ne...

The rapid progress in Virtual Reality technology has demanded more natural and effective human-computer interaction (HCI) for tasks such as display control, navigation and virtual object manipulation. Conventional interface devices such as keyboards and mice are cumbersome to use in Virtual Environments (VE). Bare hand gesturing (especially in combination with speech) is a leading candidate for...

In this article, we demonstrate a hybrid tracking method for scaled and orientated objects in video. Histogram-based mean shift can track objects quickly. However, it does not utilize shape or dynamics information and typically employs a convex bounding box, such as a rectangle or an ellipse that is decoupled from object scale and orientation. Active shape models and particle filters cope with ...

As one of the most salient features of human face, eyes play an important role in interpreting and understanding a person’s desires, needs, and emotional states. In this paper, a robust real-time “coarse to fine” method based on combining the appearance-based method and SVM approach was proposed for eye detection firstly, which combining the respective strengths of different complimentary techn...
