In this paper, we propose a new feature-point based RGB-D visual odometry approach for estimating the relative camera motion from two consecutive frames. The approach differs from most feature-point based RGB-D visual odometry approaches in two key aspects: (1) we do not directly use point correspondences to compute relative motion, instead, we link each two distinct points to form a line segment,...
Visual interpretation of SAR images plays a critical role in remote sensing applications. For obtaining the image suitable for human observation, a new method of visualization for SAR images is proposed in this paper. The proposed algorithm takes a negative exponential transformation on the original SAR image. The parameter of the transformation can be computed rapidly based on the characteristic...
An adaptive media playout algorithm based on probability estimation is proposed to reduce the video playout jitter and playout halt caused by buffer underflow. It adjusts the duration of each frame according to the channel state and the estimated probability of underflow and overflow. Also it controls the playout rate range and the variation of the playout rate of the consecutive video frames to achieve...
