Problem of loss compression taking into cosideration the structural components of signal distortion and compression technique unversality

100%

Berkman L. N. , Valchuk D.

tom Vol. 3, nr 1

42-59

In the paper, the outline of novel loss compression technique presents. The technique provides new possibilities: 1) a mechanism of loss compression quality rationalization into the space of quality indices, which are selected with a special purpose, 2) a mechanism of loss compression technique universality in sense of compressed signal heterogeneity and replacement of compression tasks of an end user. Besides those, a significant indication of the technique is its possibility of a signal structural distortion consideration. To realize this indication, we have selected pseudo-information measure JeK and studded its possibilities as a loss compression criterion for non-media signals. The measure exhibits several features that match experimental findings in multimedia perception.
