3D Video Loops from Asynchronous Input

no code implementations CVPR 2023 Li Ma, Xiaoyu Li, Jing Liao, Pedro V. Sander

Looping videos are short video clips that can be looped endlessly without visible seams or artifacts.

Water Simulation and Rendering from a Still Photograph

no code implementations5 Oct 2022 Ryusuke Sugimoto, Mingming He, Jing Liao, Pedro V. Sander

We propose an approach to simulate and render realistic water animation from a single still input photograph.

Deblur-NeRF: Neural Radiance Fields from Blurry Images

1 code implementation CVPR 2022 Li Ma, Xiaoyu Li, Jing Liao, Qi Zhang, Xuan Wang, Jue Wang, Pedro V. Sander

We demonstrate that our method can be used on both camera motion blur and defocus blur: the two most common types of blur in real scenes.

Microshift: An Efficient Image Compression Algorithm for Hardware

1 code implementation20 Apr 2021 Bo Zhang, Pedro V. Sander, Chi-Ying Tsui, Amine Bermak

In our method, the image is first micro-shifted, then the sub-quantized values are further compressed.

Let's See Clearly: Contaminant Artifact Removal for Moving Cameras

no code implementations ICCV 2021 Xiaoyu Li, Bo Zhang, Jing Liao, Pedro V. Sander

This new dataset and our novel framework lead to our method that is able to address different contaminants and outperforms competitive restoration approaches both qualitatively and quantitatively.

Video Restoration

Deep Sketch-guided Cartoon Video Inbetweening

1 code implementation10 Aug 2020 Xiaoyu Li, Bo Zhang, Jing Liao, Pedro V. Sander

The key idea of the proposed approach is to estimate the dense cross-domain correspondence between the sketch and cartoon video frames, and employ a blending module with occlusion estimation to synthesize the middle frame guided by the sketch.

Image Generation Occlusion Estimation

Document Rectification and Illumination Correction using a Patch-based CNN

1 code implementation20 Sep 2019 Xiaoyu Li, Bo Zhang, Jing Liao, Pedro V. Sander

We propose a novel learning method to rectify document images with various distortion types from a single input image.

Optical Character Recognition (OCR)

Blind Geometric Distortion Correction on Images Through Deep Learning

1 code implementation CVPR 2019 Xiaoyu Li, Bo Zhang, Pedro V. Sander, Jing Liao

We propose the first general framework to automatically correct different types of geometric distortion in a single input image.

Deep Exemplar-based Colorization

1 code implementation17 Jul 2018 Mingming He, Dong-Dong Chen, Jing Liao, Pedro V. Sander, Lu Yuan

More importantly, as opposed to other learning-based colorization methods, our network allows the user to achieve customizable results by simply feeding different references.

Colorization Image Retrieval +1

Progressive Color Transfer with Dense Semantic Correspondences

3 code implementations2 Oct 2017 Mingming He, Jing Liao, Dong-Dong Chen, Lu Yuan, Pedro V. Sander

The proposed method can be successfully extended from one-to-one to one-to-many color transfer.
