JPEG 2000 and WSQ Image Compression Interoperability

Abstract

This report explores the degree of compatibility between the wavelet-based WSQ fingerprint compression standard and JPEG 2000 compression standard, with a view towards identifying coexistence or potential migration paths. Theoretical comparison of the two standards led to the introduction of three new elements into JPEG 2000. A prototype WSQ-to-JPEG 2000 transcoder that was developed exploiting these new elements was used to test the viability of transcoding, examine errors introduced, and measure changes in file size. Results of fingerprint compression with JPEG 2000 Part 1 alone and successive recompression with WSQ and JPEG 2000 Part 1 also are presented.
