1. An array camera, comprising:

  • a plurality of cameras;

    a processor configured to receive digital pixel data from the plurality of cameras via interface circuitry; and

    memory containing an image processing pipeline application;

    wherein the image processing pipeline application directs the processor to;

    obtain a set of images of a scene that include aliasing from the plurality of cameras, wherein the aliasing is different in each image;

    fuse portions of the set of images to form fused image at each of a plurality of hypothesized disparities;

    compare the portion of the fused image obtained at each hypothesized disparity to the scene captured in the set of images;

    select a hypothesized disparity at which the portion of the fused image is most similar to the scene captured in the set of images accounting for aliasing as a disparity estimate; and

    synthesize an image of the scene from a reference viewpoint using the set of images and disparity information including the disparity estimate.
