Abstract: PURPOSE: A face animation retargeting method and recording medium for the same are provided to obtain natural expression corresponding to the expression of source animation by similar target model by combination of an RBF based recursive training result and a kCCA based recursive training result. CONSTITUTION: A system inputs a source animation. The system sets up an expression pair range between the source animation and a target animation(S210). The system performs RBF(Radial Basis Function)-based analysis training about predetermined expression pair range(S220). The system performs kCCA(kernel Canonical Correlation Analysis)-based regression training about the predetermined expression pair range(S230). The system combines an RBF-based analysis training result and a kCCA-based analysis training result by blending parameters. The system generates the target animation expression(S240). [Reference numerals] (S210) Expression pair range setup; (S220) RBF training; (S230) KCCA based return; (S240) Final retargeting
Abstract translation: 目的：提供一种面部动画重定向方法及其记录介质，以通过基于RBF的递归训练结果和基于kCCA的递归训练结果的组合来获得与类似目标模型的源动画表达相对应的自然表达。 构成：系统输入源动画。 系统在源动画和目标动画之间设置表达式对范围（S210）。 系统对预定的表达对范围进行基于RBF（径向基函数）的分析训练（S220）。 系统执行关于预定表达对范围的kCCA（内核规范相关分析）回归训练（S230）。 该系统通过混合参数组合基于RBF的分析训练结果和基于kCCA的分析训练结果。 系统生成目标动画表达式（S240）。 （参考号）（S210）表达对范围设定; （S220）RBF训练; （S230）KCCA回报; （S240）最终重新定位
