We propose a method to estimate articulate object's shape and motion from visual hulls in time sequences. Visual hulls contains superfluous region which is not a part of object shape, and such region has undesirable effects on the estimation. We use a voxel feature which reduces the undesirable effects. The experimental results show our method can estimate articulate object's shape and motion correctly.
