Reconstruction of segmentally articulated structure in freeform movement with low density feature points

Though a large body of research has focused on tracking and identifying objects from the domain of colour or grey-scale images, there is a relative dearth in the literature on complex articulated/non-rigid motion reconstruction from a collection of low density feature points. In this paper, we propose a segment-based articulated matching algorithm to establish a crucial self-initialising identification in model-based point-feature tracking of articulated motion with near-rigid segments. We avoid common assumptions such as pose similarity or small motion with respect to the model, and assume no prior knowledge of a specific movement from which to restrict pose identification. Experimental results based on synthetic pose and real-world human motion capture data demonstrate the ability of the algorithm to perform the identification task. [Copyright &y& Elsevier]
