Abstract: A plurality of superpixels of an input image 310 and an object selection input 312 for selecting part of a foreground object in the input image are received. A first set of superpixels is determined as a first set of foreground seeds and second set of superpixels as first set of background seeds. The first set of background seeds is filtered to generate second set of background seeds based on geodesic distances. Superpixels of a first set of unclassified superpixels are added to the second set of background seeds to generate third set of background seeds, and superpixels of a second set of unclassified superpixels are added to the third set of background seeds to generate fourth set of background seeds based on applying a classifier on the second set of unclassified superpixels. A user may provide the foreground object selection input in the form of scribbles.

Abstract: A method comprising: enabling a first user to define a message for display to at least a second user in association with a first three-dimensional scene viewed by the first user and viewed by or viewable by the second user, wherein the message comprises user-defined message content for display and message metadata, not for display, defining first three- dimensional spatial information; and enabling rendering of the user-defined message content in a second three-dimensional scene viewed by the second user, wherein the user-defined message content moves, within the second three-dimensional scene, along a three- dimensional trajectory dependent upon the first three-dimensional spatial information and three-dimensional spatial information of the second user.

Abstract: In an example embodiment a method, apparatus and computer program product are provided. The method includes extracting a first set of target-object regions and at least one set of non-target object regions from a plurality of regions of a video content based at least on likelihood information. A plurality of unlabeled regions of the video content are classified based on the first set of target-object regions and the at least one set of non-target object regions to generate a second set of target object regions that is denser than the first set of target object regions. A model is learned for modelling at least one of the target object and non-target objects of the video content based at least on the second set of target object regions. The target object in the video content is segmented based on the model and the second set of target object regions.
