A Non-local Area Preserving Curve Flow

In this paper, we consider a kind of area preserving non-local flow for convex curves in the plane. We show that the flow exists globally, the length of evolving curve is non-increasing, and the curve converges to a circle in C∞ sense as time goes into infinity.

Local control of area-preserving maps

We present a method of control of chaos in area-preserving maps. This method gives an explicit expression of a control term which is added to a given area-preserving map. The resulting controlled map which is a small and suitable modification of the original map, is again area-preserving and has an invariant curve whose equation is explicitly known.

A Non-trigonometric, Pseudo Area Preserving, Polyline Smoothing Algorithm

A line-smoothing algorithm based on simple arithmetic is presented and its characteristics are analyzed for various implementations. The algorithm is efficient because it can be implemented using only simple integer arithmetic, with no square root or trigonometric calculations. The algorithm is applicable to graph drawing applications that require smooth polylines between graph nodes. Though th...

A Variational Formulation for a Level Set Representation of Multiphase Flow and Area Preserving Curvature Flow∗

Abstract. Variational descriptions for various multiphase level set formulations involving curvature flow are discussed. A representation of n phases using n−1 level set functions is introduced having the advantage that constraints preventing overlaps or vacuum are not needed. The representation is then used in conjunction with our variational formulation to deduce a novel level set based algor...

Moment-preserving curve detection

A method is described for deriving, from digitiied imager.objective measures that correlate strongly with simple perceptual judge-ments on the same images. Each measure is the normalized variance of animage obtained by convolving the original image with a specific localoperator. This operator is designed to optimize the correlation between theparticular percept and the objec...
