In 3-D articulated human motion tracking, the curse of dimensionality renders commonly-used particle-filter-based approaches inefficient. Also, noisy image measurements and imperfect feature extraction call for strong motion prior. We propose to learn the correlation between the right-side and the left-side human motion using partial least square (PLS) regression. The correlation effectively constrains...
Inference in 3D articulated human body tracking is challenging due to the high dimensionality and nonlinearity of the parameter-space. We propose a particle filter with Rao-Blackwellisation which marginalizes part of the state variables by exploiting the correlation between the right-side and the left-side joint Euler angles. The correlation is naturally induced by the symmetric and repetitive patterns...
