Person Re-Identification

Long-duration tracking of individuals across large sites is a challenge. Trucks of individuals from disjoint fields of view need to be linked, despite the sa...

Activity Recognition

Providing a semantic interpretation of the actions and interactions between the actors in a scene enables behavior analysis for automated decision-making. Th...

Video Tracking

Video tracking is the process of localizing an object in video at every time instant. It is a challenging problem especially when there are multiple objects ...

Dynamic Textures

One of the most important elements of modern Computer Vision is the concept of image texture, or simply texture. Depending on the task at hand (e.g. image-ba...
