Verfahren zur Quantisierung von Koeffizienten in einem digitalen Bildkodierer

摘要

The method involves dividing each image received in digital image form into groups of blocks to form a current image. A current compression coefficient value is determined, and used for initial processing. As the image processing is performed, the compression coefficient is corrected by a generated correction coefficient. The correction coefficient is a function of the difference between the number of bits produced by the preceding groups of block of codes and an estimate of the total number of bits. Correction is performed as processing continues. <IMAGE>
