METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR DISPARITY ESTIMATION OF PLENOPTIC IMAGES |
摘要 |
In an example embodiment, a method, apparatus and computer program product are provided. The method includes facilitating receipt of a plenoptic image associated with a scene, the plenoptic image including plenoptic micro-images and being captured by a focused plenoptic camera. The method includes generating plenoptic vectors for the plenoptic micro-images of the plenoptic image, where an individual plenoptic vector is generated for an individual plenoptic micro-image. The method includes assigning disparities for the plenoptic micro-images of the plenoptic image. A disparity for a plenoptic micro-image is assigned by accessing a plurality of subspaces associated with a set of pre-determined disparities, projecting a plenoptic vector for the plenoptic micro-image in the plurality of subspaces, calculating a plurality of residual errors based on projections of the plenoptic vector in the plurality of subspaces, and determining the disparity for the plenoptic micro-image based on a comparison of the plurality of residual errors. |

1. A method comprising:
facilitating receipt of a plenoptic image associated with a scene, the plenoptic image comprising a plurality of plenoptic micro-images and being captured by a focused plenoptic camera; generating a plurality of plenoptic vectors for the plurality of plenoptic micro-images of the plenoptic image, wherein an individual plenoptic vector of the plurality of plenoptic vectors is generated for an individual plenoptic micro-image of the plurality of plenoptic micro-images; and assigning disparities for the plurality of plenoptic micro-images of the plenoptic image, wherein a disparity of the disparities for a plenoptic micro-image of the plurality of plenoptic micro-images is assigned at least by:
accessing a plurality of subspaces associated with a set of pre-determined disparities, wherein a subspace of the plurality of subspaces is associated with a corresponding pre-determined disparity of the set of pre-determined disparities,projecting a plenoptic vector for the plenoptic micro-image in the plurality of subspaces associated with the set of pre-determined disparities,calculating a plurality of residual errors based on projections of the plenoptic vector in the plurality of subspaces, anddetermining the disparity for the plenoptic micro-image based on a comparison of the plurality of residual errors. |
