A real-time approach for removing sunlight flickers from sub-aquatic scenarios captured in videos is presented. For this end, a de-flickering filter is designed. The start point is a moving landscape scene.Essentially, the filtering approach is based on morphological character-istics of the caustic waves. It constructs an a-priori de-flickered imagewhich is afterwards enhanced. The algorithm employs feedback of opti-cal flow fields and brightness in order to predict a one-step-ahead valueof the brightness.
