Enhancing Visual Domain Adaptation with Source Preparation

no code implementations16 Jun 2023 Anirudha Ramesh, Anurag Ghosh, Christoph Mertz, Jeff Schneider

Our Almost Unsupervised Domain Adaptation (AUDA) framework, a label-efficient semi-supervised approach for robotic scenarios -- employs Source Preparation (SP), Unsupervised Domain Adaptation (UDA) and Supervised Alignment (SA) from limited labeled data.

Learned Two-Plane Perspective Prior based Image Resampling for Efficient Object Detection

no code implementations CVPR 2023 Anurag Ghosh, N. Dinesh Reddy, Christoph Mertz, Srinivasa G. Narasimhan

For autonomous navigation, using the same detector and scale, our approach improves detection rate by +4. 1 $AP_{S}$ or +39% and in real-time performance by +5. 3 $sAP_{S}$ or +63% for small objects over state-of-the-art (SOTA).

Leveraging Structure from Motion to Localize Inaccessible Bus Stops

1 code implementation7 Oct 2022 Indu Panigrahi, Tom Bu, Christoph Mertz

Specifically, our method learns the locations of sidewalks in a given scene by applying a segmentation model and SfM to images from bus cameras during clear weather.

Multimodal Object Detection via Probabilistic Ensembling

2 code implementations7 Apr 2021 Yi-Ting Chen, Jinghao Shi, Zelin Ye, Christoph Mertz, Deva Ramanan, Shu Kong

Object detection with multimodal inputs can improve many safety-critical systems such as autonomous vehicles (AVs).

Learning Unsupervised Multi-View Stereopsis via Robust Photometric Consistency

1 code implementation7 May 2019 Tejas Khot, Shubham Agrawal, Shubham Tulsiani, Christoph Mertz, Simon Lucey, Martial Hebert

We demonstrate our ability to learn MVS without 3D supervision using a real dataset, and show that each component of our proposed robust loss results in a significant improvement.
