Based on the original image of plants leaves, the edge detection method will be used to extract the geometrical morphology of leaves. The characteristic points of the contour can be calculated by Harris method. The characteristic points will be used to construct the cubic Bezier curve fitting of contours of leaves, the leaf vein is generated by L system. Finally, the simulation drawing of plant...

The motion planning procedure described in this paper has been developed in order to eliminate or reduce the residual vibrations of electromechanical positioning systems, without augmenting the motion time (usually imposed by production requirements), nor introducing overtime for vibration damping. The proposed technique is based on a suitable choice of the motion law assigned to the servomotor...

This paper presents a method of parameterization for online freehand drawing objects based on a piecewise cubic Bezier curve approximation. The target is to represent sketches in a compact format within a certain error tolerance with lower computation to be practically adaptable for the online graphics input. A set of user’s intended breakpoints in digital ink is firstly produced in terms of pe...

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...

Bezier curve are very strong for variety of application. Specifically in image processing it applies to object recognition, face recognition, and human gait recognition. It also works on fingerprint and other biometric system recognition. This paper presents a work to recognize digital images of human frontal faces using the approximated Bezier curve and an intelligent process of learning using...

Protopsaltis, Antonios, A.P. PhD, Computer Science Department, University of Ioannina, Greece. January, 2010. Reconstructing 3D CAD Models based on geometrically constrained cross sections Thesis Supervisor: Fudos, Ioannis. We introduce a novel approach to reconstructing 3D objects from cross sections of point clouds acquired by laser scanning. Cross sections are almost planar clusters of 3D po...
