About
The main research interests relate to the investigation and implementation of new techniques in the fields of computer vision and multimedia. Specifically, in computer vision, I address a large spectrum of themes including human-behavior analysis, action recognition, 2D/3D object detection, large-scale event detection and video analysis, etc. In multimedia, my research focuses on three aspects: multimedia information retrieval, social signals processing and affective computing.
The specific research topics include cross media retrieval, multi-modal learning, social media analysis, emotion recognition, multimodal brain-computer interfaces, etc.
