Compression impact on LIRE-based CBIR of colonoscopy data

Abstract

In a large experimental study, the impact of lossy image compression standards on LIRE-based CBIR in different compression scenarios is assessed. Image retrieval is conducted using NBI-colonoscopic imagery with the aim of polyp dignity assessment. Results clearly indicate that (1) JPEG2000 compression does hardly impact retrieval results, (2) it is important to compress both query and retrieval data in case of JPEG and JPEG XR, and (3) some LIRE desciptors deliver good retrieval results on these data which calls for further investigations.
