Motion Pattern Encapsulation for Data-Driven Constraint-Based Motion Editing

TL;DR: This work presents and discusses a new data-driven constraint-based animation system for interactive human motion editing that offers the compelling advantage that it provides faster deformations and more natural-looking motion results compared to goal-directed constraint- based methods found in the literature.

Abstract: The growth of motion capture systems have contributed to the proliferation of human motion database, mainly because human motion is important in many applications, ranging from games entertainment and films to sports and medicine. However, the captured motions normally attend specific needs. As an effort for adapting and reusing captured human motions in new tasks and environments and improving the animator's work, we present and discuss a new data-driven constraint-based animation system for interactive human motion editing. This method offers the compelling advantage that it provides faster deformations and more natural-looking motion results compared to goal-directed constraint-based methods found in the literature.

1. What are the contributions mentioned in the paper "Motion pattern encapsulation for data-driven constraint-based motion editing" ?

As an effort for adapting and reusing captured human motions in new tasks and environments and improving the animator ’ s work, the authors present and discuss a new data-driven constraintbased animation system for interactive human motion editing.. This method offers the compelling advantage that it provides faster deformations and more natural-looking motion results compared to goal-directed constraint-based methods found in the literature.

2. What future works have the authors mentioned in the paper "Motion pattern encapsulation for data-driven constraint-based motion editing" ?

By making use of the pattern space, the authors increased the possibilities of performing IK in the space of feasible poses.. For example, the authors have retarget a golf swing motion to a 7◦ up slope using constraints that can not be satisfied directly by any motion in the database, and have found that the quality of the generated motion was believable.

Fig. 5. Pink arrow shows the current foot position and the red shows the sliding gap

Fig. 2. (a) Once the LPIK converges to a {αυk} satisfying all the constraints of a pose k, the system uses Eq. 4 to recover the deformed pose: Θυk = α υ kEΨ +Ψ◦. The process is repeated frame by frame. (b) Motion editing from specific key-time constraints. The complete animation {Ψυ} is computed as: Ψυ = αυEΨ +Ψ◦.

Fig. 6. Fist row shows the input and the generated motion by the PIK-based system. Second row the same for the LPIK-based system. The pink arrow shows the current foot position, the red the sliding gap and the blue the anticipation.

Fig. 4. The initial hit position is illustrated by a transparent ball. In both methods the golfer hits the ball (a,b), but with the PIK the club head hit the ground (b).
