摘 要：We begin this thesis with the development of a system that is capable of categorizing objects and landmarks in an efficient and distributed manner.In the second part of the thesis we extend our distributed object categorization framework to address the problem of automatic human activity detection and categorization.In most realistic scenarios that require situation awareness, objects and people occur in cluttered scenes and exhibit immense variability in their appearance, shape and pose. In the final part of this thesis, we analyze the interplay between computer vision tasks such as segmentation and categorization and present joint frameworks that significantly improve the performance of each task.
