Zusammenfassung

Compression settings for sample (probe) finger vein data in case of already pre-compressed gallery data are investigated. Inhomogeneous compression scenarios are assessed where probe data can be compressed with different compression technique and compression ratio compared to gallery data using 4 lossy compression schemes, 2 finger vein recognition schemes, and 2 data sets. Results obtained indicate that in case of JPEG2000 pre-compressed gallery, also sample images should be compressed in the same manner, while for JPEG pre-compressed gallery, the optimal sample compression setting depends on the dataset, on the target compression ratio, and on the recognition scheme employed.
