The High-Quality Wide Multi-Channel Attack (HQ-WMCA) database

This provides a new dataset for researchers in biometrics and security to test attack detection methods, but it is incremental as it builds on an existing database.

The authors introduced the HQ-WMCA database, which extends the WMCA database by adding more channels like color, depth, thermal, infrared, and short-wave infrared, along with a wide variety of attacks.
