APPD: Adaptive and Precise Pupil Boundary Detection using Entropy of Contour Gradients
Cihan Topal, Halil Ibrahim Cakir, Cuneyt Akinlar
Eye tracking spreads through a vast area of applications from ophthalmology, assistive technologies to gaming and virtual reality. Precisely detecting the pupil's contour and cente…
STag: A Stable Fiducial Marker System
Burak Benligiray, Cihan Topal, Cuneyt Akinlar
Fiducial markers provide better-defined features than the ones naturally available in the scene. For this reason, they are widely utilized in computer vision applications where rel…
SliceType: Fast Gaze Typing with a Merging Keyboard
Burak Benligiray, Cihan Topal, Cuneyt Akinlar
Jitter is an inevitable by-product of gaze detection. Because of this, gaze typing tends to be a slow and frustrating process. In this paper, we propose SliceType, a soft keyboard…
Greedy Search for Descriptive Spatial Face Features
Caner Gacav, Burak Benligiray, Cihan Topal
Facial expression recognition methods use a combination of geometric and appearance-based features. Spatial features are derived from displacements of facial landmarks, and carry g…
Lens Distortion Rectification using Triangulation based Interpolation
Burak Benligiray, Cihan Topal
Nonlinear lens distortion rectification is a common first step in image processing applications where the assumption of a linear camera model is essential. For rectifying the lens…
