Paper Abstract

Data compression is quite relevant for storage and transmission of museal data. This work reports on the performance of subband coding applied to paintings pictures obtained by an HDTV camera. The performance of different analysis/synthesis filter banks and coding schemes is compared. The best results are obtained via Johnston's filters and a uniform threshold quantizer. The effectiveness of a scalable use of subband coding in this application is also reported.
