摘要
Coding quantized transform coefficients as occur in image compression combines a position coding method to code the position of clusters of consecutive non-zero-valued coefficients with an amplitude coding method to code the amplitudes of a concatenation of a plurality of the clusters. The amplitude coding method exploits that runs of amplitude 1 coefficients are more likely in the clusters than runs of other coefficient amplitudes.
