Research on Low-light Image Enhancement Algorithms and Implementation Based on FPGA
Jingxiang Wang, Yu Liu · 2025
Enhancing image quality is critical for ensuring accurate detection, monitoring, and analysis of visual data. This study begins with an examination of Low-Light Image Enhancement (LLIE) algorithms, focusing on brightness and contrast adjustment techniques. Four representative image enhancement algorithms are modeled and simulated in MATLAB, followed by a comparative analysis of their strengths and limitations. The histogram equalization algorithm is selected for implementation based on its superior performance in the evaluation. Finally, the algorithm is deployed on a Field Programmable Gate Array (FPGA) platform, and experimental results confirm the feasibility of real-time histogram processing in hardware.
