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.

Towards Fast and Accurate Ellipse and Semi-Ellipse Detection
2018 25th IEEE International Conference on Image Processing (ICIP), 2018Ellipse detection is an important task in machine vision and can be used to solve other high-level visual problems. In the past, many studies have been conducted by researchers at high precision ellipse fitting, but most of the proposed solutions are not fast enough to be applied in real-time detection for larger images or with limited hardware ...

With the aid of a duality relation originally obtained in the theory of statistical experimental design, an exact terminating algorithm is developed for finding the ellipse of smallest area covering a given plane point set. Some applications and related problems are discussed.

1. Introduction The perimeter of an ellipse has always posed challenges due to the lack of a simple, closed formula. In this study, a new geometric method is proposed, based on an intuitive physical model that relates an ellipse to a square surrounded by an elastic circular ring under uniform pressure. --- 2.
