Fancy Man Launches Zippo at WNUT 2020 Shared Task-1: A Bert Case Model for Wet Lab Entity Extraction

no code implementations EMNLP (WNUT) 2020 Qingcheng Zeng, Xiaoyang Fang, Zhexin Liang, Haoding Meng

Automatic or semi-automatic conversion of protocols specifying steps in performing a lab procedure into machine-readable format benefits biological research a lot.

Control Color: Multimodal Diffusion-based Interactive Image Colorization

no code implementations16 Feb 2024 Zhexin Liang, Zhaochen Li, Shangchen Zhou, Chongyi Li, Chen Change Loy

We also introduce a novel module based on self-attention and a content-guided deformable autoencoder to address the long-standing issues of color overflow and inaccurate coloring.

Iterative Prompt Learning for Unsupervised Backlit Image Enhancement

no code implementations ICCV 2023 Zhexin Liang, Chongyi Li, Shangchen Zhou, Ruicheng Feng, Chen Change Loy

To solve this issue, we devise a prompt learning framework that first learns an initial prompt pair by constraining the text-image similarity between the prompt (negative/positive sample) and the corresponding image (backlit image/well-lit image) in the CLIP latent space.

Embedding Fourier for Ultra-High-Definition Low-Light Image Enhancement

no code implementations23 Feb 2023 Chongyi Li, Chun-Le Guo, Man Zhou, Zhexin Liang, Shangchen Zhou, Ruicheng Feng, Chen Change Loy

Our approach is motivated by a few unique characteristics in the Fourier domain: 1) most luminance information concentrates on amplitudes while noise is closely related to phases, and 2) a high-resolution image and its low-resolution version share similar amplitude patterns. Through embedding Fourier into our network, the amplitude and phase of a low-light image are separately processed to avoid amplifying noise when enhancing luminance.
