Abstract :
Naming image compression´s state of the art surely leads to JPEG2000. This new format takes advantage of the discrete wavelet transform to overtake all the compression methods that have been used up to now. This article proposes two changes in the processing chain to deal with sparse histogram images: one nested in Tier-1 coding, the other between coefficient coding and MQ-coder.
