Research Paper Overview
Vision At Night: Exploring Biologically Inspired Preprocessing For Improved Robustness Via Color And Contrast Transformations
Summary
Inspired by the human visual system's mechanisms for contrast enhancement and color-opponency, this paper explores biologically motivated input preprocessing for robust semantic segmentation. By applying Difference-of-Gaussians (DoG) filtering to RGB, grayscale, and opponent-color channels, local contrast is enhanced without modifying model architecture or training. Evaluations on Cityscapes, ACDC, and Dark Zurich datasets show that such preprocessing maintains in-distribution performance while improving robustness to adverse conditions like night, fog, and snow. This model-agnostic and lightweight processing can be integrated into imaging pipelines to deliver task-ready, robust inputs for downstream vision models in safety-critical environments.
