Particle filters (PF) are widely used in the vision literature for visual object tracking. However, the selection and the tuning of the observation PDF (or likelihood function) involved in the particle weighting stage are often eclipsed. These considerations have a strong influence on the tracking performance, especially for human motion capture (HMC) due to the high number of degrees of freedom and...
This paper presents a new non-photorealistic/stroke-based rendering (NPR/SBR) framework for the stylization of videos featuring head shots of people, such as home videos, movies, and camera mobile phone clips. Spatiotemporal skin and edge detection are used to locate and emphasize the semantic content in the stylization process. The SBR portion of the algorithm features novel techniques for motion...
Embodied conversational agents are fast growing area of research interest. These agents allow interacting with computers in a natural way. The usage of agents is closely associated with the problem of facial animation. Realistic real-time facial animation is very computational expensive. This work is dedicated to the problem of deformation visualization of pseudo-muscles and head model mesh during...
