Convolutional networks tremendously boosted the classification accuracy in the recent years. My goal is to exploit their inherent knowledge for other tasks like part discovery and localization. Our ACCV and ICCV paper published in 2014 and 2015 show the huge potential of this approach.
My work focuses on fine-grained classification, which is the automated recognition of visually very similar object categories like bird species or car models. I concentrate on improving state-of-the-art approaches especially in the scenario of weakly annotated images.
A core ingredient of most fine-grained classification approaches are object part locations. In order to improve classification accuracy, my research also includes finding the most discriminative object parts without the need of annotations provided by humans. This will allow for transferring the extensive knowledge of fine-grained recognition approaches to generic classification tasks.
Besides pure research, I also contribute to the development of products at my chair’s partners in industry. A document classification system and a road segmentation system are examples for that.
