METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR DISPARITY ESTIMATION IN IMAGES

摘要

In an example embodiment, a method, apparatus and computer program product are provided. The method includes facilitating receipt of an image of a scene and determining a graph based on connecting nodes of the image. The nodes are either pixels or superpixels of the image. The graph is determined by determining one or more connections of a node to one or more nodes belonging to a pre-defined image region around the node in the image. The connections are associated with edge weights that are determined based on at least one of similarity parameters and spatial distances between the node and the one or more nodes. The method includes determining disparity values at the nodes of the image based at least on performing tree based aggregation of a cost volume on the graph, where the cost volume is associated with the image and at least one view image of the scene.

1. A method comprising:
facilitating receipt of an image of a scene; determining a graph based on connecting a plurality of nodes of the image, the plurality of nodes being pixels or superpixels of the image, wherein determining the graph comprises determining one or more connections of a node of the plurality of nodes to one or more nodes of the plurality of nodes, the one or more nodes belonging to a pre-defined image region around the node in the image, the one or more connections being associated with corresponding edge weights determined based on at least one of similarity parameters and spatial distances between the node and the one or more nodes; and determining disparity values at the plurality of nodes of the image based at least on performing a tree based aggregation of a cost volume on the graph, the cost volume associated with the image and at least one view image of the scene, the at least one view image comprising a different view of the scene than a view of the scene in the image.
