[Other] spline-basedImageRegistration DL : 0: The problem of image registration subsumes a number of problems and techniques in multiframe image analysis, including the computation of optic flow (general pixel-based motion), stereo correspondence, structure from motion, and feature tracking. We present a new registration algorithm based on spline representations of the displacement field which can be specialized to solve all of the above mentioned problems. In particular, we show how to compute local flow, global (parametric) flow, rigid flow resulting from camera egomotion, and multiframe versions of the above problems. Using a spline-based description of the flow removes the need for overlapping correlation windows, and produces an explicit measure of the correlation between adjacent flow estimates. We demonstrate our algorithm on multiframe image registration and the recovery of 3D projective scene geometry. We also provide results on a number of standard motion sequences.

[Other] Multi-Target-Tracking DL : 0: Most of my current work focuses on tracking pedestrians mobile platforms. The idea is to equip robots or cars with vision systems that can oversee the traffic situation around the car and that can give an early warning for dangerous situations. The system finds people, tracks them, and determines their trajectory relative to the mobile platform which the images are taken. We tested our system in busy urban scenarios, and provide the corresponding dataset for other researchers. The underlying methodology is to integrate different functionalities that thus far have been mainly developed separately in computer vision: recognition - tracking - 3D reconstruction for egomotion extraction. -Most of my current work focuses on tracking pedestrians mobile platforms.
