A Higher-Order Active Contour Model for Tree Detection
We present a model of a `gas of circles', the ensemble of regions in the image domain consisting of an unknown number of circles with approximately fixed radius and short ran...

A Markov Random Field Model for Extracting Near-Circular Shapes
We propose a binary Markov Random Field (MRF) model that assigns high probability to regions in the image domain consisting of an unknown number of circles of a given radius. We...

Improving Arc Detection in Graphics Recognition
In the context of graphics recognition, arc detection consists in the extraction of circles and arcs from the image of a graphics document or from the segments yielded by its vect...

Fast Focal Length Solution in Partial Panoramic Image Stitching
Accurate estimation of effective camera focal length is crucial to the success of panoramic image stitching. Fast techniques for estimating the focal length exist, but are depende...

Eye Gaze Estimation from a Single Image of One Eye
In this paper, we present a novel approach, called the “one-circle” algorithm, for measuring the eye gaze using a monocular image that zooms in on only one eye of a person. Ob...
