An analysis of contemporary JPEG2000 codecs for image format migration
This paper presents results of an analysis of different implementations of the JPEG2000 standard, specifically part 1: JP2, an image format that is currently popular within the digital preservation community. In particular we are interested in the effect different JPEG2000 codecs (encoders and decoders) have on image quality in response...Palmer, William ; May, Peter ; Cliff, Peter

Practical analysis of TIFF file size reductions achievable through compression
This paper presents results of a practical analysis into the effects of three main lossless TIFF compression algorithms – LZW, ZIP and Group 4 – on the storage requirements for a small set of digitized materials. In particular we are interested in understanding which algorithm achieves a greater reduction in...May, Peter ; Davies, Kevin
