In video images, apparent motions can be computed using optical flow estimation. However, estimation of the depth directional velocity is difficult using only a single viewpoint. Scene flows (SF) are three-dimensional (3D) vector fields with apparent motion and a depth directional velocity field, which are computed from stereo video. The 3D motion of(More)
Diffuse idiopathic skeletal hyperostosis (DISH) is a common skeletal disorder in the elderly, which can develop into periosteal hyperostosis and paradoxically into immobilization-associated trabecular osteoporosis. The bone anabolic agent, teriparatide (TPD), seems to be a rational treatment for the immobilization-associated osteoporosis. However, it can(More)
This paper proposes a method to improve the prediction accuracy of motion compensation (MC) in video coding using block-wise and pixel-wise motion with little additional information. In general MC, block-wise motion vectors (MVs) are computed by block matching (BM), but these are not always suitable for motions such as local scaling and deformation. To(More)
