Raw point data collected by 3D scanning techniques are usually rendered by building an interpolating robust polygonal mesh. This approach is accurate and fast but provides no means for large scale subsequent modifications. Only local interactive or non-interactive tools are provided that are usually targeted to correcting small imperfections and eliminating noise effects. CAD applications requi...

In this paper, an efficient and adjustable visual image encryption scheme is proposed by combining a 6D hyperchaotic system, compressive sensing, Bezier curve embedding. First, the plain sparse discrete wavelet transform (DWT). Then, encrypted compressed through game-of-life (GOL) hybrid scrambling sensing into cipher image. Next, embedding utilized to embed carrier in domain. After these opera...

As one of the key components heat pump system, compared to that a conventional axial fan, blade tip area forward-swept fan is much larger than its root, which main noise source and also has an important influence on efficiency. Enhancement aerodynamic performance efficiency was addressed by utilizing Bezier function parameterize curve tops. In order quickly select agent model suitable for proje...

In this work, a new adaptive integration method for simulation of two-dimensional linear elasticity problems is presented. The main benefit the proposed reduction computational cost by lowering number points required to reach certain level accuracy. concept calculate weights trimmed cells employing advantage Bezier parametric curves. Within concept, it possible map square triangle with one curv...

In this paper, a new technique has been designed to capture the outline of 2D shapes using cubic B´ezier curves. The proposed technique avoids the traditional method of optimizing the global squared fitting error and emphasizes the local control of data points. A maximum error has been determined to preserve the absolute fitting error less than a criterion and it administers the process of curv...
