.This paper is concerned with the range restricted interpolation of 'data on rectangular grids. The interpolant is constrained to lie on the same side of the constraint surface as the data. Sufficient non-negativity conditions on the Bezier ordinates are derived to ensure the non-negativity of a bicubic Bezier patch. The method modifies Bezier ordinates locally to fulfill the sufficient non-neg...

Iris is a strong biometric tool used for human authentication. In this methodology, the patterns in the iris such as rings, furrows and freckles can be envisaged a set of Bezier curves and hence represented by the corresponding Bezier points, resulting in considerable reduction in the file size. After the iris is captured using scanner, the patterns are extracted from the scanned image. Then th...

This paper proposed an efficient, intelligent and less complex method of face recognition. A hybrid approach of face recognition is proposed here using the neural networks and Bezier curves. Detection of structural facial features such as eyes, eyebrows, nose, lips and mouth boundaries is an essential process for various image processing task such as face recognition. In this paper we introduce...

We present two practical path planning algorithms based on Bezier curves for autonomous vehicles operating under waypoints and corridor constraints. Bezier curves have useful properties for the trajectory generation problem. This paper describes how the algorithms apply these properties to generate the reference trajectory for vehicles to satisfy the path constraints. Both algorithms generate t...

We study Bezier surfaces defined over triangular domains. We have seen how spaces of bivariate polynomials can be constructed as tensor-products of the univariate ones. An alternative choice of polynomial space is, for each n ≥ 0, the space of polynomials of the form p(x, y) = 0≤i+j≤n a i,j x i y j , where we understand that i ≥ 0 and j ≥ 0 in the summation. As in the univariate case, we denote...

-In this paper, we will present a simple and quick sampling method to digitize the cubic Bezier curves via controlled the chordal error. Key-Words: sampling method, chordal error, cubic Bezier curve

The use of Bezier curves and Bezier triangles has been extensively explored in the field of computer graphics. The purpose of this paper is to show that Bezier triangles and curves can be used for reducing the cost of Biquadratic Phong shading. A shading algorithm has been proposed which uses quadratic Bezier triangle’s blending functions for performing quadratic interpolation of normal vector ...

Fingerprint and Iris are significant biometric tools used for authentication. This paper proposes a novel methodology by which the biometric patterns can be visualized as a set of Bezier curves and hence represented by the corresponding Bezier points, resulting in considerable reduction in the file size. This scheme utilizes the Bezier curve representations for effective compression of all thos...

The creative industries have become the government's attention for contributing to economic accretion. But due lack of artistic creativity and appeal, evolution craft section is not optimal. So that it was needed a variations relief items increase attractiveness. In general, industrial objects design are still limited space geometry or Bezier curve degree two. Therefore, curves selected modifie...
