In response to the rapid change of attitude in complex situations such as sharp turns and camera jitter, visual odometry/visual simultaneous localization and mapping (VO/VSLAM) often requires a high camera frame rate.However, the high frame rate of the camera poses a great challenge to real-time VO/VSLAM, especially when the vehicle travels along a

Unlabeled sensing is a linear inverse problem where Header Modeling Set the measurements are scrambled under an unknown permutation leading to loss of correspondence between the measurements and the rows of the sensing matrix.Motivated by practical tasks such as mobile sensor networks, target tracking and the pose and correspondence estimation betw
