Abstract
A computerized method compresses an input sequence of 2-D images captured by a monocular camera. The input sequence of images includes a moving articulated 3-D figure. A pose of the figure in each image is registered using a 2-D scaled prismatic model to produce a state trajectory for the figure in each image of the input sequence. The state trajectory of the figure in the images is reconstructed to determine kinematic parameters of a 3-D kinematic model that best fit the state trajectories, The 3-D kinematic model represents the 3-D movement of the figure in the input sequence of 2-D images. Static information of a first image of the input sequence is encoded. For subsequent images of the input sequence, a time series of state vectors containing the kinematic parameters of the moving figure are encoded. The static information of the first image and the time series of state vectors can be used to generate an output sequence of images including the moving articulated 3-D figure on a viewing device.
