SFRC-Flow: Spatial–Frequency Dual-Domain Refinement and Motion Prior Calibration for Low-Light Optical Flow Estimation
Optical flow estimation is a fundamental task in computer vision and visual sensing systems. However, most existing approaches are designed for normal illumination conditions. In low-light scenarios, inherent imaging noise and low contrast lead to noticeable feature degradation and matching ambiguity, which compromise...
