运动捕捉数据对动画师很有用，因为它捕捉特定个体运动的确切风格，并具有逼真的质量。然而，通常数据并不完全是动画师所需要的。我们演示了一种方法，用于创建合成运动数据，解决了这个问题，通过允许动画师指定硬约束，如脚应该接触地板的起点，使用运动捕捉数据。该方法捕捉的运动风格，以及生活般的质量。它从分析阶段开始，在该阶段中，数据被划分为诸如频带和关节角度之间的相关性等特征，并用基于多维核的概率分布表示。然后在合成阶段对这些分布进行采样，并进行优化以产生最终的动画。
Motion capture data is useful to an animator because it captures the exact style of a particular individual’s movements and has a life-like quality. However, often the data is not exactly what the animator needs. We demonstrate a method for using motion capture data as a starting point for creating synthetic motion data that addresses this problem by allowing the animator to specify hard constraints such as where the feet should contact the floor. The method captures the style of the motion as well as the life-like quality. It begins with an analysis phase, in which the data is divided into features such as frequency bands and correlations among joint angles, and represented with multidimensional kernel-based probability distributions. These distributions are then sampled in a synthesis phase, and optimized to yield the final animation.
