Dark-ISP: Enhancing RAW Image Processing for Low-Light Object Detection

Guo jiasheng, Xin Gao, Yuxiang Yan, Guanghao Li, Jian Pu

Project

  • Dark-ISP is a lightweight and self-adaptive Image Signal Processing (ISP) plugin designed to improve low-light object detection. Unlike previous methods that either use RAW-RGB images with information loss or complex frameworks, Dark-ISP processes Bayer RAW images directly in dark environments. Its key innovations include deconstructing conventional ISP pipelines into linear and nonlinear sub-modules optimized for task-driven losses, and a self-boosting strategy that enhances cooperation between sub-modules.
