Texture compression is an important technique in graphics processing units (GPUs) for saving memory bandwidth. This paper presents a high-quality mipmapping texture compression (MTC) system with alpha maps. Based upon the wavelet transform, a hierarchical approach is adopted for mipmapping textures in the YCbCr color space and alpha channel. By inspecting the similarity between the alpha and luminance channels, the two channels are efficiently encoded together with linear prediction in the… CONTINUE READING
