“…Computer vision can be applied to various domains, such as, Virtual Reality, Robotics, Desktop and Tablet applications, Games, Sign Languages, among others [13]. Solutions based on ordinary webcams [14], infrared sensors (Leap Motion) [15] or depth sensors (Kinect and RealSense 3D) [16] [17] were already implemented in the literature. Cameras represent a less intrusive solution, since the user is completely equipment free but, once data is obtained from the cameras, the quality and reliability of this data have a great dependency over the environment light, the capture distance/perspective and even the camera quality.…”
