Model Overview
Zero-DCE is a deep learning method that enhances low-light images by estimating high-order tone curves without requiring reference images, preserving dynamic range and contrast.
Model Features
Reference-free Training
Does not require input/output image pairs for training; guided by reference-free loss functions
Dynamic Range Preservation
Preserves the dynamic range of images through high-order tone curve estimation
Contrast Retention
Retains contrast between adjacent pixels during enhancement
Lightweight Network
Uses a lightweight DCE-Net for pixel-level curve estimation
Model Capabilities
