As Face Recognition(FR) technology becomes more mature and commercially available in the market, many different anti-spoofing techniques have been recently developed to enhance the security, reliability, and effectiveness of FR systems. As a part of anti-spoofing techniques, face liveness detection plays an important role to make FR systems be more secured from various attacks. In this paper, we propose...
Since 3D data has additional depth information than 2D image, it can be used various researches and applications such as robot vision, car navigation and human computer interaction. Especially, 3D face recognition is robust against facial pose and light variation since it can use 3D face shape information such as facial profile, curvature and depth map. However, it is difficult to acquire 3D face...
Detecting and tracking fingertips are significant techniques for recognizing hand gestures. Many patterns and skin color information are used to extract and trace features. However, to find correct shapes is difficult and there is limitation to express the diversity of models. In this paper, we describe a method of detecting and tracking fingertips based on Active Shape Models (ASMs) and an ellipse...
