Evaluation of accurate eye corner detection methods for gaze estimation [PDF]
, 2014 Accurate detection of iris center and eye corners appears to be a promising approach for low cost gaze estimation. In this paper we propose novel eye inner corner detection methods. Appearance and feature based segmentation approaches are suggested.

Curvature scale space corner detector with adaptive threshold and dynamic region of support [PDF]
, 2004 Corners play an important role in object identification methods used in machine vision and image processing systems. Single-scale feature detection finds it hard to detect both fine and coarse features at the same time.

An Asynchronous Real-Time Corner Extraction and Tracking Algorithm for Event Camera
Sensors, 2021 Event cameras have many advantages over conventional frame-based cameras, such as high temporal resolution, low latency and high dynamic range. However, state-of-the-art event- based algorithms either require too much computation time or have poor ...

Robust Detection of Corners and Corner-line Links in Images [PDF]
2010 10th IEEE International Conference on Computer and Information Technology, 2010 We define corner points in an image as the intersections among detected straight line segments, and propose an algorithm that detects corners from such a definition. Our corner detection algorithm CLDC then makes use of the LDC (Line Detection using Contours) algorithm from [19], which outputs the list of all detected line segments together with their ...
