Anurag Das

I am currently, a PhD student at the Computer vision group at MPI Informatics in Saarbrucken, supervised by Prof. Bernt Schiele. Prior to that, I was a part of preparatory phase of Saarbrucken Graduate School of Computer Science. I did my bachelor's in Information Technology from IIIT Allahabad from 2013-17. My research focuses on Label Efficient Learning for vision tasks such as semantic segmentation, object detection etc.

Weakly-Supervised Domain Adaptive Semantic Segmentation with Prototypical Contrastive Learning
Anurag Das, Yongqin Xian, Dengxin Dai, Bernt Schiele
CVPR, 2023

We propose a common framework to use different weak labels, e.g., image, point and coarse labels from the target domain to reduce the performance gap between UDA and supervised learning.

Urban Scene Semantic Segmentation with Low-Cost Coarse Annotation

WACV, 2023

We propose to utlize cheaper coarse annotations for urban scene semantic segmentation. Coarse annotation lacks fine Boundary details and are faster to annotate. Our proposed method obtains competitive performance with coarse annotation along with relatively free synthetic data compared with fine annotation at a fraction of the annotation budget.

(SP)2Net for Generalized Zero-Label Semantic Segmentation
Anurag Das, Yongqin Xian, Yang He, Zeynep Akata, Bernt Schiele
GCPR, 2021 [ Best Master Thesis Award in Germany]

Generalized Zero-shot Semantic Segmentation(GZSS) is a challenging problem as the prior works don't generalize well on unseen classes. we propose to leverage a class-agnostic segmentation prior provided by superpixels and introduce a superpixel pooling (SP-pooling) module that improves the performance on GZSS task.
