Abstract

There is provided techniques for updating background layers during encoding of scene, performed by an image processing device. The scene is encoded based on classifying objects depicted in the scene as either foreground or background. The background is divided into ordered background layers where each background layer is associated with a respective depth model. The method comprises detecting (S102) a change in an image portion of one background layer. The method comprises calculating (S104) a difference between the image portion and a corresponding image portion of a background layer ordered behind said one background layer. The method comprises selecting (S106a), when the difference is smaller than a threshold, said background layer ordered behind said one background layer to represent the image portion.
