Learning Image-adaptive 3D Lookup Tables for High Performance Photo Enhancement in Real-time

1 code implementation30 Sep 2020 Hui Zeng, Jianrui Cai, Lida Li, Zisheng Cao, Lei Zhang

The small CNN works on the down-sampled version of the input image to predict content-dependent weights to fuse the multiple basis 3D LUTs into an image-adaptive one, which is employed to transform the color and tone of source images efficiently.

Dark and Bright Channel Prior Embedded Network for Dynamic Scene Deblurring

1 code implementation21 May 2020 Jianrui Cai, WangMeng Zuo, and Lei Zhang

In this work, we propose a Dark and Bright Channel Priors embedded Network (DBCPeNet) to plug the channel priors into a neural network for effective dynamic scene deblurring.

CameraNet: A Two-Stage Framework for Effective Camera ISP Learning

no code implementations5 Aug 2019 Zhetong Liang, Jianrui Cai, Zisheng Cao, Lei Zhang

Traditional image signal processing (ISP) pipeline consists of a set of individual image processing components onboard a camera to reconstruct a high-quality sRGB image from the sensor raw data.

Toward Real-World Single Image Super-Resolution: A New Benchmark and A New Model

no code implementations ICCV 2019 Jianrui Cai, Hui Zeng, Hongwei Yong, Zisheng Cao, Lei Zhang

Most of the existing learning-based single image superresolution (SISR) methods are trained and evaluated on simulated datasets, where the low-resolution (LR) images are generated by applying a simple and uniform degradation (i. e., bicubic downsampling) to their high-resolution (HR) counterparts.

Extreme Channel Prior Embedded Network for Dynamic Scene Deblurring

no code implementations2 Mar 2019 Jianrui Cai, WangMeng Zuo, Lei Zhang

In this work, we propose an Extreme Channel Prior embedded Network (ECPeNet) to plug the extreme channel priors (i. e., priors on dark and bright channels) into a network architecture for effective dynamic scene deblurring.

Learning a Single Tucker Decomposition Network for Lossy Image Compression with Multiple Bits-Per-Pixel Rates

no code implementations10 Jul 2018 Jianrui Cai, Zisheng Cao, Lei Zhang

By changing the rank of the core tensor and its quantization, we can easily adjust the bpp rate of latent image representation within a single CNN.
