Combined data association and evolving particle filter for tracking of multiple articulated objects. [PDF]

open access: yes, 2011
This paper proposes an approach for tracking multiple articulated targets using a combined data association and evolving population particle filter. A visual target is represented as a pictorial structure using a collection of parts together with a model

Combining Particle Filter and Population-based Metaheuristics for Visual Articulated Motion Tracking

open access: yesELCVIA Electronic Letters on Computer Vision and Image Analysis, 2005
Visual tracking of articulated motion is a complex task with high computational costs. Because of the fact that articulated objects are usually represented as a set of linked limbs, tracking is performed with the support of a model.
