In the process of printed matter quality inspection. the influence of lighting conditions leads to a large color difference between the captured image and the actual image. Therefore. this paper proposes an illumination correction model based on Remora Optimization Algorithm for Regularized Extreme Learning Machine (ROA-RELM). https://www.jmannino.com/amazing-price-Handlebar-for-Motovox-MBX10-and-MBX11-Mini-Bikes-amazing-deal/
