In this paper, the task of Mission 7 of International Aerial Robotics Competition (IARC) is investigated. The quadrotor is required to autonomously navigate in a GPS-denied environment, and accomplish physical interaction with ground moving targets. In order to estimate the position of the quadrotor, a multi-sensor-compensation based method is designed and individual measurement errors are compensated...
Undeniability is an essential security property of the traditional digital signature. Strong designated verifier signature(DSVS) is a special digital signature in where the validity of a signature can only be checked by the designated verifier. However, most strong DSVS schemes do not have the undeniability property which leads to dispute between a designated verifier and a signer. In this study,...
Traditional hand vein recognition technology is usually based on 2D infrared images in which the hand vein patterns are unavoidable distorted with hand posture changes. Point cloud matching vein recognition based on Kernel Correlation method provides a new perspective to hand vein recognition but also suffers from posture change. In this paper, a 3D point cloud registration algorithm is proposed to...
