GBU Dataset

The GBU (Good, Bad and Ugly) database consists of parts of the MBGC-V1 image set. It defines three protocols, i.e., Good, Bad and Ugly for which different model and probe images are used.

Setting up the database

To use this dataset protocol, you need to have the original files of the IJBC datasets. Once you have it downloaded, please run the following command to set the path for Bob

bob config set bob.bio.face.gbu.directory [GBU PATH]

Benchmarking

You can run the mobio baselines command with a simple command such as:

bob bio pipeline simple gbu-good iresnet100

Open Source Face Recognition Library has some customized plots where the FMR and FNMR trade-off in the evaluation set can be plot using operational FMR thresholds from the development set. This is done be the command bob bio face plots gbu command as in the example below:
