Abstract
Described is systems and methods for determining the depth of pixels captured in a plenoptic image. The systems and methods may provide a plurality of views of each pixel location in the plenoptic image. One way of providing the plurality of views is to obtaining pixel intensities from the views for each pixel location in the plenoptic image. A variance can then be calculated of the distribution of pixel intensities for each pixel position. If the variance is below a predetermined threshold, the systems may mask out at least one depth plane and then recalculate the variance in the distribution of pixel intensities to determine if the variance is below the threshold.
