Patent ID: 8811769

Claim:
A method for removing artifacts in two-dimensional images projected from light-field data, comprising: a) at a processor, retrieving a two-dimensional image projected from light-field data; b) at the processor, generating at least one reduced-resolution representation of the two-dimensional image, each reduced-resolution representation comprising a plurality of pixels, each pixel having a value; c) for each reduced-resolution representation of the two-dimensional image, performing the steps of: c.1) for each pixel in the reduced-resolution representation, identifying a plurality of corresponding target pixels in a higher-resolution representation, each target pixel having a value; c.2) for each identified target pixel, determining an influence metric; and c.3) for each identified target pixel, responsive to the influence metric of the target pixel being less than a predetermined threshold value, replacing the value of the target pixel with a weighted sum of its value and the value of the corresponding pixel in the reduced-resolution representation; and d) storing the higher-resolution image in a storage device.
