Among the various types of semantic concepts modeled, events pose the greatest challenge in terms of computational power needed to represent the event and accuracy that can be ach...
We consider detection of moving ground vehicles in airborne sequences recorded by a thermal sensor with automatic gain control, using an approach that integrates dense optic flow...
A novel approach is presented to select multiple key frames within an isolated video shot where there is camera motion causing significant scene change. This is achieved by determ...
We describe a system for analyzing human driver alertness. It relies on optical flow and color predicates to robustly track a person’s head and facial features. Our system clas...
With the advent of sophisticated and low-cost video editing software, it is becoming increasingly easier to tamper with digital video. In addition, an ever-growing number of video...
