Differentiable Hybrid Traffic Simulation

no code implementations14 Oct 2022 Sanghyun Son, Yi-Ling Qiao, Jason Sewall, Ming C. Lin

To compute the gradient flow between two types of traffic models in a hybrid framework, we present a novel intermediate conversion component that bridges the lanes in a differentiable manner as well.

AP-BSN: Self-Supervised Denoising for Real-World Images via Asymmetric PD and Blind-Spot Network

2 code implementations CVPR 2022 Wooseok Lee, Sanghyun Son, Kyoung Mu Lee

Extensive studies demonstrate that our method outperforms the other self-supervised and even unpaired denoising methods by a large margin, without using any additional knowledge, e. g., noise level, regarding the underlying unknown noise.

C2N: Practical Generative Noise Modeling for Real-World Denoising

1 code implementation ICCV 2021 Geonwoon Jang, Wooseok Lee, Sanghyun Son, Kyoung Mu Lee

In a practical scenario, a noise generator should learn to simulate the general and complex noise distribution without using paired noisy and clean images.
