摘要：

为了在移动平台中得到高质量、高实时性的纹理显示，设计并实现了一种基于查找表的各向异性纹理映射方法。该方法通过改变归一化椭圆足迹模型的自变量选择，精确测量各参数量化对图像质量的影响，由此建立查找表获得足迹组合滤波中的所需参数。在此基础上，根据系统有效带宽的限制，加入动态调节纹理映射带宽需求的参数选择功能。实验表明，该滤波方法显示质量高，计算复杂度低，且具有带宽可控的优点，适于移动平台实现。

Abstract:

In order to get high quality images on a mobile platform, an anisotropic texture mapping filter based on lookup table (LUT) is proposed. First, the new parameters of a normalized elliptical footprint model are selected to quantify the shape of the pixel footprint. Then the LUT is set up which contains the parameters of footprints assembly, such as position and average weight etc. On this basis, a parameter selection method is proposed, which can fit for the bandwidth limits of the system dynamically. Experimental results show that this algorithm could generate high quality images and is suitable for mobile platforms due to its low computation complexity.
