Toward Generalized Image Quality Assessment: Relaxing the Perfect Reference Quality Assumption

1 code implementation CVPR 2025 Du Chen, Tianhe Wu, Kede Ma, Lei Zhang

To relax the assumption of perfect reference image quality, we build a large-scale IQA database, namely DiffIQA, containing approximately 180, 000 images generated by a diffusion-based image enhancer with adjustable hyper-parameters.

SSL: A Self-similarity Loss for Improving Generative Image Super-resolution

1 code implementation11 Aug 2024 Du Chen, Zhengqiang Zhang, Jie Liang, Lei Zhang

Based on the fact that natural images exhibit high self-similarities, i. e., a local patch can have many similar patches to it in the whole image, in this work we propose a simple yet effective self-similarity loss (SSL) to improve the performance of generative Real-ISR models, enhancing the hallucination of structural and textural details while reducing the unpleasant visual artifacts.

Deep Neural Network for Fast and Accurate Single Image Super-Resolution via Channel-Attention-based Fusion of Orientation-aware Features

no code implementations9 Dec 2019 Du Chen, Zewei He, Yanpeng Cao, Jiangxin Yang, Yanlong Cao, Michael Ying Yang, Siliang Tang, Yueting Zhuang

Firstly, we proposed a novel Orientation-Aware feature extraction and fusion Module (OAM), which contains a mixture of 1D and 2D convolutional kernels (i. e., 5 x 1, 1 x 5, and 3 x 3) for extracting orientation-aware features.
