Abstract
A scene is segmented into objects based on light field data for the scene, including based on image pixel values (e.g., intensity) and disparity map(s). In one aspect, the light field data is used to estimate one or more disparity maps for the scene taken from different viewpoints. The scene is then segmented into a plurality of regions that correspond to objects in the scene. Unlike other approaches, the regions can be variable-depth. In one approach, the regions are defined by boundaries. The boundaries are determined by varying the boundary to optimize an objective function for the region defined by the boundary. The objective function is based in part on a similarity function that measures a similarity of image pixel values for pixels within the boundary and also measures a similarity of disparities for pixels within the boundary.
