Explorative Inbetweening of Time and Space

no code implementations21 Mar 2024 Haiwen Feng, Zheng Ding, Zhihao Xia, Simon Niklaus, Victoria Abrevaya, Michael J. Black, Xuaner Zhang

We introduce bounded generation as a generalized task to control video generation to synthesize arbitrary camera and subject motion based only on a given start and end frame.

Magic Fixup: Streamlining Photo Editing by Watching Dynamic Videos

no code implementations19 Mar 2024 Hadi AlZayer, Zhihao Xia, Xuaner Zhang, Eli Shechtman, Jia-Bin Huang, Michael Gharbi

We show that by using simple segmentations and coarse 2D manipulations, we can synthesize a photorealistic edit faithful to the user's input while addressing second-order effects like harmonizing the lighting and physical interactions between edited objects.

Restoration by Generation with Constrained Priors

no code implementations CVPR 2024 Zheng Ding, Xuaner Zhang, Zhuowen Tu, Zhihao Xia

We propose a method to adapt a pretrained diffusion model for image restoration by simply adding noise to the input image to be restored and then denoise.

DiffusionRig: Learning Personalized Priors for Facial Appearance Editing

1 code implementation CVPR 2023 Zheng Ding, Xuaner Zhang, Zhihao Xia, Lars Jebe, Zhuowen Tu, Xiuming Zhang

On a high level, DiffusionRig learns to map simplistic renderings of 3D face models to realistic photos of a given person.

Semi-supervised Parametric Real-world Image Harmonization

no code implementations CVPR 2023 Ke Wang, Michaël Gharbi, He Zhang, Zhihao Xia, Eli Shechtman

Learning-based image harmonization techniques are usually trained to undo synthetic random global transformations applied to a masked foreground in a single ground truth photo.

Self-Supervised Burst Super-Resolution

no code implementations ICCV 2023 Goutam Bhat, Michaël Gharbi, Jiawen Chen, Luc van Gool, Zhihao Xia

Extensive experiments on real and synthetic data show that, despite only using noisy bursts during training, models trained with our self-supervised strategy match, and sometimes surpass, the quality of fully-supervised baselines trained with synthetic data or weakly-paired ground-truth.

The Implicit Values of A Good Hand Shake: Handheld Multi-Frame Neural Depth Refinement

1 code implementation CVPR 2022 Ilya Chugunov, Yuxuan Zhang, Zhihao Xia, Xuaner, Zhang, Jiawen Chen, Felix Heide

Modern smartphones can continuously stream multi-megapixel RGB images at 60Hz, synchronized with high-quality 3D pose information and low-resolution LiDAR-driven depth estimates.

A Dark Flash Normal Camera

no code implementations ICCV 2021 Zhihao Xia, Jason Lawrence, Supreeth Achar

Casual photography is often performed in uncontrolled lighting that can result in low quality images and degrade the performance of downstream processing.

Deep Denoising of Flash and No-Flash Pairs for Photography in Low-Light Environments

no code implementations CVPR 2021 Zhihao Xia, Michaël Gharbi, Federico Perazzi, Kalyan Sunkavalli, Ayan Chakrabarti

We introduce a neural network-based method to denoise pairs of images taken in quick succession, with and without a flash, in low-light environments.

Training Image Estimators without Image Ground Truth

1 code implementation NeurIPS 2019 Zhihao Xia, Ayan Chakrabarti

Deep neural networks have been very successful in compressive-sensing and image restoration applications, as a means to estimate images from partial, blurry, or otherwise degraded measurements.

Compressive Sensing Image Restoration

Generating and Exploiting Probabilistic Monocular Depth Estimates

1 code implementation CVPR 2020 Zhihao Xia, Patrick Sullivan, Ayan Chakrabarti

Beyond depth estimation from a single image, the monocular cue is useful in a broader range of depth inference applications and settings---such as when one can leverage other available depth cues for improved accuracy.

Training Image Estimators without Image Ground-Truth

1 code implementation13 Jun 2019 Zhihao Xia, Ayan Chakrabarti

We evaluate our method for training networks for compressive-sensing and blind deconvolution, considering both non-blind and blind training for the latter.

Identifying Recurring Patterns with Deep Neural Networks for Natural Image Denoising

1 code implementation13 Jun 2018 Zhihao Xia, Ayan Chakrabarti

In this work, we propose a new method for natural image denoising that trains a deep neural network to determine whether patches in a noisy image input share common underlying patterns.
