Real-world Noisy Image Denoising: A New Benchmark

2 code implementations7 Apr 2018 Jun Xu, Hui Li, Zhetong Liang, David Zhang, Lei Zhang

In order to promote the study on this problem while implementing the concurrent real-world image denoising datasets, we construct a new benchmark dataset which contains comprehensive real-world noisy images of different natural scenes.

A Benchmark for Edge-Preserving Image Smoothing

1 code implementation2 Apr 2019 Feida Zhu, Zhetong Liang, Xixi Jia, Lei Zhang, Yizhou Yu

This benchmark includes an image dataset with groundtruth image smoothing results as well as baseline algorithms that can generate competitive edge-preserving smoothing results for a wide range of image contents.

A Benchmark for Chinese-English Scene Text Image Super-resolution

1 code implementation ICCV 2023 jianqi ma, Zhetong Liang, Wangmeng Xiang, Xi Yang, Lei Zhang

Scene Text Image Super-resolution (STISR) aims to recover high-resolution (HR) scene text images with visually pleasant and readable text content from the given low-resolution (LR) input.

Joint HDR Denoising and Fusion: A Real-World Mobile HDR Image Dataset

1 code implementation CVPR 2023 Shuaizheng Liu, Xindong Zhang, Lingchen Sun, Zhetong Liang, Hui Zeng, Lei Zhang

In this work, we develop, for the first time to our best knowledge, an HDR image dataset by using mobile phone cameras, namely Mobile-HDR dataset.

Joint Denoising and Demosaicking with Green Channel Prior for Real-world Burst Images

1 code implementation25 Jan 2021 Shi Guo, Zhetong Liang, Lei Zhang

Considering the fact that the green channel has twice the sampling rate and better quality than the red and blue channels in CFA raw data, we propose to use this green channel prior (GCP) to build a GCP-Net for the JDD-B task.

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.

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.
