EllSeg: An Ellipse Segmentation Framework for Robust Gaze Tracking. (arXiv:2007.09600v2 [cs.CV] UPDATED)

Web: http://arxiv.org/abs/2007.09600

Ellipse fitting, an essential component in pupil or iris tracking based video
oculography, is performed on previously segmented eye parts generated using
various computer vision techniques. Several factors, such as occlusions due to
eyelid shape, camera position or eyelashes, frequently break ellipse fitting
algorithms that rely on well-defined pupil or iris edge segments. In this work,
we propose training a convolutional neural network to directly segment entire
elliptical structures and demonstrate that such a framework is robust to
occlusions and …
