Sumario:A real-time approach for removing sunlight flickers from subaquatic 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 characteristics of the caustic waves. It constructs an a-priori de-flickered image which is afterwards enhanced. The algorithm employs feedback of optical flow fields and brightness in order to predict a one-step-ahead value of the brightness.
