| 摘 要： | 不同于传统的计算机动画，非真实感动画通常不需要精确的三维模型和光照模型，因此，用户希望自己能够生成简单的非真实感动画。基于这种需求，将定向滤波引入到非真实感动画中：利用一对正交的定向滤波核与源图像进行卷积运算，产生一对奇偶滤波图像，并通过不断改变其相位得到一系列运动的图像，使图像内的物体在实际位置并不发生改变的情况下，产生视觉上的动画效果，从而方便地生成非真实感动画。

| Abstract: | Different to traditional computer animation, accurate 3D models and illumination models were not requested in non-photorealistic animation, so some users hoped to create simple NPA by themselves. Based on this requirement, this paper introduced steerable filters: generated a pair of even and odd filtered images by convoluting a quadrature pair of steerable filters with a source image, and then through continuously varying their phases over time, it gave the vision of an object in motion without changing its position. Created the animation conveniently in this way. |
