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.

Grid Anchor based Image Cropping: A New Benchmark and An Efficient Model

1 code implementation18 Sep 2019 Hui Zeng, Lida Li, Zisheng Cao, Lei Zhang

The employed evaluation metrics such as intersection-over-union cannot reliably reflect the real performance of a cropping model, either.

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.

Reliable and Efficient Image Cropping: A Grid Anchor based Approach

1 code implementation CVPR 2019 Hui Zeng, Lida Li, Zisheng Cao, Lei Zhang

Consequently, a grid anchor based cropping benchmark is constructed, where all crops of each image are annotated and more reliable evaluation metrics are defined.

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.

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.

A Hybrid l1-l0 Layer Decomposition Model for Tone Mapping

no code implementations CVPR 2018 Zhetong Liang, Jun Xu, David Zhang, Zisheng Cao, Lei Zhang

State-of-the-art tone mapping algorithms mostly decompose an image into a base layer and a detail layer, and process them accordingly.
