CONSTRAIN PROPAGATION FOR GHOST REMOVAL IN HIGH DYNAMIC RANGE IMAGES

Abstract

Creating high dynamic range images of non-static scenes is a challenging task. Carefully preventing strong camera shakes during shooting and performing image-registration before combining the exposures cannot ensure that the resulting HDR image is consistent. This is eventually due to the presence of moving objects in the scene that causes the so called ghosting artifacts. Currently there is no robust solution that produces satisfactory results in any circumstance. Our method consists of two main steps. First, the probability of belonging to the static part of the scene is estimated for each pixel of the N exposures, yielding N weight images. In the second phase, we segment the areas of the weight-images with lower and higher probability values, and smoothly propagate their influence until a significant change in luminosity is detected or a pixel with a corresponding high probability of belonging to the background is approached. This represents an attempt to spread the influence of lower weights to the surrounding pixels of the same object. Results produced with our technique show a significant reduction or total removal of ghosting artifacts.
