L 2 ESTIMATES ON CHORD - ARC CURVES 227 Theorem
We characterize those domains in the plane whose boundary is a chord arc curve in terms of some L 2 integrals, which are mainly a version of Green's theorem. As a consequence of this we obtain a \converse" to a theorem due to Laurentiev that states that for such domains harmonic measure and arc length are A 1 equivalent. Let ? be a locally rectiiable Jordan curve in the plane that passes throug...
متن کاملEfficient piecewise linear approximation of space curves using chord and arc length
abstract An efficient, accurate, and simple method for doing suboptimal piecewise linear approximation of open or closed space curves is described. The algorithm guarantees approximation within a deviation threshold and is offered as an efficient alternative to the popular, but inefficient, split and merge approach. The several efficient alternatives this author encountered are defined only for...
متن کاملSingle chord-based corner detectors on planar curves
Detecting corner locations in the images plays a significant role in several computer vision applications such as motion detection, image registration, video tracking, image mosaicing, panorama stitching and object recognition. In this paper we have analyzed an existing state of art, Chord to Point Distance Accumulation (CPDA) corner detector and modified this detector in way that it uses a sin...
متن کاملCurves with rational chord-length parametrization
It has been recently proved that rational quadratic circles in standard Bézier form are parameterized by chord-length. If we consider that standard circles coincide with the isoparametric curves in a system of bipolar coordinates, this property comes as a straightforward consequence. General curves with chord-length parametrization are simply the analogue in bipolar coordinates of nonparametric...
متن کاملA chord-arc covering theorem in Hilbert space
We prove that there exists M > 0 such that for any closed rectifiable curve Γ in Hilbert space, almost every point in Γ is contained in a countable union of M chord-arc curves whose total length is no more than Ml(Γ). Mathematics Subject Classification (2000): 28A75
