Michael B. Holte has with success defended his Ph.D. thesis entitled “Vision-Based 2D and 3D Human Activity Recognition”, i.a. based on four articles published in recognised journals.
From the thesis summary:
“Automatic analysis and recognition of human activities facilitates many applications, and thus has received great interest from both industry and research communities. The focus of this thesis is on video-based human activity recognition, i.e. automatic analysis and understanding of activities performed by people and recorded by video.
The activities are recorded by standard color cameras, multi-view camera setups, and time-of-flight range cameras, enabling analysis of both 2D and 3D video data.”
