Because circular objects are projected to ellipses in images, ellipse fitting is a first step for 3-D analysis of circular objects in computer vision applications. For this reason, the study of ...

In this paper, fast ellipse fitting based pupil tracking design is studied for human-computer interaction applications. The proposed scheme uses the two-stage Random Sample Consensus (RANSAC) based ...

Ellipse detection and fitting constitute essential components in the computer vision toolkit, enabling the precise localisation of elliptical shapes within images.
