A Velocital Preconditioner for Reducing Artifacts Introduced by Dct-based Compression

The Discrete Cosine Transform (DCT) along with frame diierencing, normal-ization and quantization are used in a variety of video compression techniques that are designed for image sequences. These techniques produce lower quality image sequences suuering from artifacts such as blocking, frame repeats, blurring, image persistence and edge business. The… CONTINUE READING
