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…
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…
