摘　　要：作为一种独特的动画表现形式,非真实感动画通常不需要精确的三维模型和光照模型,但又需要普通用户能方便地生成简单的非真实感动画。根据这一需求,将定向滤波技术与非真实感动画相结合:将源图像与一对正交的定向滤波进行卷积运算,得到一对奇偶滤波图像,反复改变它们的相位生成一系列不同相位的图像,使图像中的对象产生视觉上的动态效果,从而方便生成非真实感动画。As a unique animation style, accurate 3D models and illumination models are not requested in non-photorealistic animation, so, some researchers hope to help the ordinary users to create simple NPA conveniently. Based on this requirement, steerable filters are introduced to the generation of NPA： A pair of even and odd filtered images is generated by convoluting a quadrature pair of steerable filters with a source image, and then through continuously varying their phases over time, the vision of an object in motion is given without changing its position. Animation is conveniently created in this way.
