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.
