WorDepth: Variational Language Prior for Monocular Depth Estimation

1 code implementation4 Apr 2024 Ziyao Zeng, Daniel Wang, Fengyu Yang, Hyoungseob Park, Yangchao Wu, Stefano Soatto, Byung-Woo Hong, Dong Lao, Alex Wong

To test this, we focus on monocular depth estimation, the problem of predicting a dense depth map from a single image, but with an additional text caption describing the scene.

Monitored Distillation for Positive Congruent Depth Completion

1 code implementation30 Mar 2022 Tian Yu Liu, Parth Agrawal, Allison Chen, Byung-Woo Hong, Alex Wong

In the absence of ground truth for model selection and training, our method, termed Monitored Distillation, allows a student to exploit a blind ensemble of teachers by selectively learning from predictions that best minimize the reconstruction error for a given image.

Generative Adversarial Networks via a Composite Annealing of Noise and Diffusion

no code implementations1 May 2021 Kensuke Nakamura, Simon Korman, Byung-Woo Hong

Based on these observations, we propose a data representation for the GAN training, called noisy scale-space (NSS), that recursively applies the smoothing with a balanced noise to data in order to replace the high-frequency information by random data, leading to a coarse-to-fine training of GANs.

A New Model and Simple Algorithms for Multi-label Mumford-Shah Problems

no code implementations CVPR 2013 Byung-Woo Hong, Zhaojin Lu, Ganesh Sundaramoorthi

The advantage of this statistical model is that the underlying variables: the labels and the functions are less coupled than in the original formulation, and the labels can be computed from the functions with more global updates.
