A hybrid method for ellipse detection in industrial images
Pattern Recognition, 2017 Many ellipse detection methods have been proposed for detecting ellipses in images. However, they are unsuitable for industrial images due to low signal-to-noise ratios (SNR).

We address the problem of how to cover a set of "required points" by a small number of "axis-parallel ellipses" that avoid a second set of "forbidden points". We study geometric properties of such covers and present an efficient randomized approximation algorithm for the cover construction.

Ellipse, arc of ellipse and elliptic spline
Computers & Graphics, 1983Abstract A general method for generating ellipses by using conjugate radii is presented. Elliptical arcs are then defined based on this method for generating ellipses. A 90° arc of ellipse is then used to generate a number of curves with slope constraints. Other arc of ellipse interpolations are then discussed.

An incision is described in which the two ends of an elliptical excision are displaced. This can be used in two situations; in the reduction in length of one side of a digit and in the excision of two lesions close together.

Optical centroid ellipses beyond polarization ellipses
Optics LettersPolarization ellipses are well-known as the result of coherent superposition of photonic spin states. As orbital counterparts, in this Letter, we introduce centroid ellipses that are geometrically mapped from optical orbital angular momentum (OAM) superpositions on a modal Poincaré sphere (PS) by coaxial interference.
