DVI image compression: second generation

摘要

Abstract: The goal of this compression algorithm is to exploit the i750$+TM$/ video processor to achieve VCR quality video at CD-ROM data rates. The algorithm uses motion compensation with fractional-pixel displacements to produce good predicted images. The residual errors are then encoded using pyramid and vector-quantization techniques. A binary tree is used to efficiently encode large areas of the image with the same displacement vector, and large areas where the residual errors quantize to zero. The remaining quantities are statistically encoded for the programmable statistical decoder of the i750 video processor. This second-generation algorithm has achieved its goal and is now incorporated in current DVI products.!2
