A robust eye-corner detection method for real-world data
Gil Santos, Hugo Proença · 2011
Corner detection has motivated a great deal of research and is particularly important in a variety of tasks related to computer vision, acting as a basis for further stages. In particular, the detection of eye-corners in facial images is important in applications in biometric systems and assisted- driving systems. We empirically evaluated the state-of-the-art of eye-corner detection proposals and found that they achieve satisfactory results only when dealing with high-quality data. Hence, in this paper, we describe an eye-corner detection method that emphasizes robustness, i.e., its ability to deal with degraded data, and applicability to real-world conditions. Our experiments show that the proposed method outperforms others in both noise-free and degraded data (blurred and rotated images and images with significant variations in scale), which is a major achievement.
