Abstract: There are disclosed various methods, apparatuses and computer programs for processing video information. In an embodiment of the method a first video stream representing a left view of a part of a scene and a second video stream representing a right view of the part of the scene are received. Optical enhancement data regarding image pairs of the first video stream and the second video stream and transform data for warping at least one of the left view and the right view are obtained (514). The first video stream and the second video stream are warped (516-522) on the basis of the optical enhancement data and the transform data.

Abstract: The invention relates to methods, apparatuses and computer program products for rendering of digital image and video content. First information of a first graphic object for rendering a second graphic object and second information of the second graphic object for rendering the second graphic object are formed or received. Dependency information between the first and second graphic objects is formed or received, where the dependency information comprises information for rendering the second graphic object depending on overlapping of said first graphic object and the second graphic object in a viewing direction. The second graphic object is rendered by creating second pixel data using the second information of the second graphic object and the first information of the first graphic object, where the rendering of the second graphic object is carried out for such part of the second graphic object that is overlapped by the first graphic object in the viewing direction.

Abstract: The invention relates to forming a scene model and determining a first group of scene points, the first group of scene points being visible from a rendering viewpoint, determining a second group of scene points, the second group of scene points being at least partially obscured by the first group of scene points viewed from the rendering viewpoint, forming a first render layer using the first group of scene points and a second render layer using the second group of scene points, and providing the first and second render layers for rendering a stereo image.
