Abstract: We present an algorithm for quickly compressing textures into PVRTC, the Imagination PowerVR Texture Compression format. Our formulation is based on intensity dilation and exploits the notion that the most important features of an image are those with high contrast ratios. We present an algorithm that uses morphological operations to distribute the areas of high contrast into the compression parameters. We use our algorithm to compress into PVRTC textures and compare our performance with prior techniques in terms of speed and quality.
