Abstract :
This study presents a novel method for controlling the effect of outdoor illumination on object color hues by using an external white LED illumination to adapt to changing outdoor illumination. Outdoor illumination varies with shadows and cloud movements passing the sunlight. Gradual or sudden changes in illumination in outdoor applications influence image hues and colors, which, in turn, affect the intended classification results. In this study, graphs show that the images taken at 10.00am with external white LED illumination exhibited a similar curve pattern with images taken at 12.00pm whereas for images taken without white LED illumination displayed an individual curve pattern at different capture times. This suggests that the external white LED illumination provided a color correction effect against gradual illumination changes in outdoor application.
