Fine-grained Recognition

Team

Dimitri Korsch, Julia Böhlke, Paul Bodesheim

Motivation

In this research area, we are developing methods that are able to automatically distinguish between very similar object categories. The algorithms learn from given pictures and their annotations the locations as well as the characteristics of relevant features. Applications for this research include automatic biodiversity monitoring.
