This paper introduces a novel segmentation method for deformable objects in monocular infrared videos.First,the concept of dynamic shape is proposed to implicitly represent spatial-temporal correlation.The logistic principal component analysis optimizes the mapping from high dimensional shape space to latent subspace,where an autoregressive model is established to predict the deformation.Then the shape prior term is formulated as a distance of deformation by explicitly estimating integral motion of the whol...
