WeatherProof: A Paired-Dataset Approach to Semantic Segmentation in Adverse Weather

no code implementations15 Dec 2023 Blake Gella, Howard Zhang, Rishi Upadhyay, Tiffany Chang, Matthew Waliman, Yunhao Ba, Alex Wong, Achuta Kadambi

To this end, we create the WeatherProof Dataset, the first semantic segmentation dataset with accurate clear and adverse weather image pairs, which not only enables our new training paradigm, but also improves the evaluation of the performance gap between clear and degraded segmentation.

Enhancing Diffusion Models with 3D Perspective Geometry Constraints

no code implementations1 Dec 2023 Rishi Upadhyay, Howard Zhang, Yunhao Ba, Ethan Yang, Blake Gella, Sicheng Jiang, Alex Wong, Achuta Kadambi

We show that outputs of models trained with this constraint both appear more realistic and improve performance of downstream models trained on generated images.

pCON: Polarimetric Coordinate Networks for Neural Scene Representations

no code implementations CVPR 2023 Henry Peters, Yunhao Ba, Achuta Kadambi

Neural scene representations have achieved great success in parameterizing and reconstructing images, but current state of the art models are not optimized with the preservation of physical quantities in mind.

WeatherStream: Light Transport Automation of Single Image Deweathering

no code implementations CVPR 2023 Howard Zhang, Yunhao Ba, Ethan Yang, Varan Mehra, Blake Gella, Akira Suzuki, Arnold Pfahnl, Chethan Chinder Chandrappa, Alex Wong, Achuta Kadambi

We introduce a pipeline that uses the power of light-transport physics and a model trained on a small, initial seed dataset to reject approximately 99. 6% of unwanted scenes.

Depth Estimation From Camera Image and mmWave Radar Point Cloud

no code implementations CVPR 2023 Akash Deep Singh, Yunhao Ba, Ankur Sarker, Howard Zhang, Achuta Kadambi, Stefano Soatto, Mani Srivastava, Alex Wong

To fuse radar depth with an image, we propose a gated fusion scheme that accounts for the confidence scores of the correspondence so that we selectively combine radar and camera embeddings to yield a dense depth map.

MIME: Minority Inclusion for Majority Group Enhancement of AI Performance

no code implementations1 Sep 2022 Pradyumna Chari, Yunhao Ba, Shreeram Athreya, Achuta Kadambi

A common misconception is that minority inclusion does not increase performance for majority groups alone.

Not Just Streaks: Towards Ground Truth for Single Image Deraining

1 code implementation22 Jun 2022 Yunhao Ba, Howard Zhang, Ethan Yang, Akira Suzuki, Arnold Pfahnl, Chethan Chinder Chandrappa, Celso de Melo, Suya You, Stefano Soatto, Alex Wong, Achuta Kadambi

We propose a large-scale dataset of real-world rainy and clean image pairs and a method to remove degradations, induced by rain streaks and rain accumulation, from the image.

Synthetic Generation of Face Videos With Plethysmograph Physiology

no code implementations CVPR 2022 Zhen Wang, Yunhao Ba, Pradyumna Chari, Oyku Deniz Bozkurt, Gianna Brown, Parth Patwa, Niranjan Vaddi, Laleh Jalilian, Achuta Kadambi

Accelerated by telemedicine, advances in Remote Photoplethysmography (rPPG) are beginning to offer a viable path toward non-contact physiological measurement.

Overcoming Difficulty in Obtaining Dark-skinned Subjects for Remote-PPG by Synthetic Augmentation

no code implementations10 Jun 2021 Yunhao Ba, Zhen Wang, Kerim Doruk Karinca, Oyku Deniz Bozkurt, Achuta Kadambi

Camera-based remote photoplethysmography (rPPG) provides a non-contact way to measure physiological signals (e. g., heart rate) using facial videos.

Visual Physics: Discovering Physical Laws from Videos

no code implementations27 Nov 2019 Pradyumna Chari, Chinmay Talegaonkar, Yunhao Ba, Achuta Kadambi

In this paper, we teach a machine to discover the laws of physics from video streams.

Blending Diverse Physical Priors with Neural Networks

1 code implementation1 Oct 2019 Yunhao Ba, Guangyuan Zhao, Achuta Kadambi

Such generalization would require an architecture that can adapt to variations in the correctness of the physics, or in the quality of training data.
