... Kovar et al. [18]. A motion graph for motion capture data is a graph structure to organize the motion capture data for editing. In [16, 17], the node in motion graph is a frame in motion capture data ... database according to the parsed motion structure. Therefore, the user can select the desired motions (called key motions) from the motion database. A motion graph is co...

... searching for local minima in the degree of motion. Searching for local minima in kinematical parameters was a reasonable approach because motion speed decreases for a moment when the motion type ... elegant. Therefore, it is difficult to set appropriate fixed values for thresholding for any type of motion. Therefore, we employ relative comparison we have developed in [22, 25]...

... ty−x t 2.1 exists for each x, y ∈ S and in this case E is said to be smooth. E is said to have a uniformly Frechet differentiable norm if the limit 2.1 is attained uniformly for x, y ∈ S and ... x, y ∈ S and in this case E is said to be uniformly smooth. It is well known that if E is uniformly smooth, then the duality map is norm-to-norm uniformly continuous on bounded subsets of E....

The resulting action model consists of a representative manifold for the action, namely, the mean performance, the standard deviation from the mean performance. ... human motion for the bending action. The model learns a mean-performance for the synchronized training set and its observed variance at each posture. In Figure 5(d) the learnt acti...
