While region-based image alignment algorithms that use gradient descent can achieve sub-pixel accuracy when they converge, their convergence depends on the smoothness of the image intensity values. Image smoothness is often enforced through the use of multi-scale approaches in which images are smoothed and downsampled. Yet, these approaches typically use(More)
This year, the University of Central Florida participated in the high level feature extraction task (HLF). The goal of high level feature extraction is to identify in videos specific shots that contain concepts such as " bus, " " person playing soccer, " and " boat/ship. " In our submissions, we focused on addressing the large imbalance between the positive(More)
