Method and apparatus for limiting data rate and image quality loss in lossy compression of sequences of digital images

摘要: By limiting the extent to which degree of quantization is lowered increase amount compressed data, problems data rate overshoots and image quality degradation in multi layer composites may be avoided. In particular, when a more complex occurs after simple image, used compress will not cause as large change total data. Recovery from such also occur quickly. Where tables are adjusted using scaling factor, limit on factor established that target achieved for images. When rendering composites, this recompression previously does result additional loss information. As result, each composite same table composite.
