We propose a novel tracking algorithm called slide window tracker (SWT) suitable for maneuvering target. To efficiently estimate trajectory of moving target, we adopt a sliding piecewise linear window which includes past trace information. By adjusting the window parameters, the proposed algorithm is to reduce measurement noise and to track fast maneuvering target with little computational increment...
This paper deals with the geometric issue of the contact between a wheel and a rail joint. A new model in this field is proposed. Actually, the wheel and rail elasticity is introduced in order to overcome the singularity of the contact force that is met in the classical approaches. The coordinates of the bicontact zone are calculated from nonlinear set equations derived from the Hertz's theory. This...
A video sequence consists of several hundred frames and as a result creating a panoramic image from these frames is a very time consuming process. Consecutive frames have large overlap areas which do not provide much information. Therefore, some key frames must be extracted for better performance. There are a number of methods for key frame selection, which match all frames in a video sequence. In...
In this paper, we present two new filtered back-projection (FBP) type algorithms for cylindrical detector helical cone-beam geometry with no position dependent backprojection weight. The algorithms are extension of the recent exact Hilbert filtering based 2D divergent beam reconstruction with no back-projection weight to the FDK type algorithm for reconstruction in 3D helical trajectory cone-beam...
In this paper, the special estimation schemes for INS/GPS integration is addressed and implemented on real-time PC-box hardware. The strapdown INS (SINS) using two Kalman filters (KF) has been built so that the system can be operated flexibly between feed-forward and feedback modes in case of GPS outage. The experiment results shown that this INS/GPS system can be used for practical applications.
