My current research areas at CVAP are representation and matching of image structures in multi-scale frameworks. One research focus is on new types of image descriptors, the work is done in collaboration with Oskar Linde and Tony Lindeberg.
Earlier, my research has included efficient methods for multi-scale feature detection and feature tracking using adaptive scale selection, multi-scale feature hierarchies for object representation, 3D motion estimation from feature trajectories in monocular sequences and computer vision based human-computer interaction.
My research in computer vision based HCI has been focused on the choice, representation and recognition of hand gestures for use in human-computer interfaces based on intentional, semiotic gestures, and the usability of such interfaces in different scenarios, such as the control of home appliances and consumer electronics. This research was carried out at the former Centre for User Oriented IT Design (CID), now the HCI group at KTH.
During the last ten years I've spent most of my time engaged in a number of companies commercialising computer vision research results, e.g. automotive safety systems for driver inattention and fatigue detection based on face and gaze tracking, and computer vision based applications for mobile phones and handheld computers.
A list of selected publications can be found here , most of them can be downloaded from the list of publications from CVAP. My PhD thesis from 1999 has the title "Multi-Scale Feature Tracking and Motion Estimation" .
