Bézier curve flattening by recursive subdivision requires that the maximum excursion of the subdivided curve segment be known so that recursion can be terminated once this value drops below the specified flatness criterion. A much more accurate method than the most commonly used techniques to evaluate this distance is presented. This method stops recursion sooner, significantly reducing the num...

Extracting and understanding of emotion is of high importance for the interaction among human and machine communication systems. The most expressive way to display the human’s emotion is through facial expression analysis. This paper presents and implements an automatic extraction and recognition method of facial expression and emotion from still image. There are two steps to recognize the faci...

Image inpainting is a technique for restoring damaged old photographs and removing undesired objects from an image. The basic idea behind the technique is to automatically fill in lost or broken parts of an image using information from the surrounding area. The challenge of current inpainting algorithms is to restore both texture and structure characteristic information for large and thick dama...

There are many studies to approximate sine curve or wave. In this study, it has been examined the way how wave can be written as any order Bezier curve. First, 5th and 7th degree Maclaurin series expansion of parametric form Also, they paths, based on control points with matrix in E2. Hence given coefficients curves three steps. Further too.

The distance between two objects is an important problem in CAGD, CAD and CG etc. It will be presented in this paper that a simple and quick method to estimate the distance between a point and a Bezier curve on a Bezier surface. Keywords—Geodesic-like curve, distance, projection, Bezier.

The history of modal intervals goes back to the very first publications on the topic of interval calculus. The modal interval analysis is used in Computer graphics and Computer Aided Design (CAD), namely, the computation of narrow bounds on Bezier and B-Spline curves. Since modal intervals are used in many fields, we introduce a new sequence space h(gI) called the Hahn sequence space of modal i...

In this study, we propose a new algorithm for image denoising by using double stranded Bezier curves based smoothing technique. The is developed to solve energy minimization problems with non-smooth total variation norm (TV). In order demonstrate the efficiency of apply it some numerical examples. experimental results are reported and they compared obtained from TV ...

Approximation of helices has been studied by using in many ways. In this study, it examined how a circular helix can be written as Bezier curve and the 3th degree, 5th 7th degree Maclaurin series expansions for polynomial forms. Hence, they cubic, order, order curves, based on control points with matrix form we have already given E3. Further coefficients expansion helix.
