Tracking unknown moving targets on omnidirectional vision

This paper presents an integrated method by using optical flow and kernel particle filter (KPF) to detect and track moving targets in omnidirectional vision. According to the circle character in omnidirectional image, the algorithms of optical flow fields and kernel particle filter are improved based on the polar coordinates at the omnidirectional center. The edge of a motion object can be dete...

On behalf of the entire Editorial Board,wewould like to thank Thieme for their past services to GSJ and EBSJ over the last 5 yea...

Moving Cs50 into the Cloud

In Fall 2008, we moved Harvard College’s introductory computer science course, CS50, into the cloud. Rather than continue to rely on our own instructional computing infrastructure on campus, we created a load-balanced cluster of virtual machines (VMs) for our 330 students within Amazon Elastic Compute Cloud (EC2). Our goals were both technical and pedagogical. As computer scientists, we wanted ...
