Abstract
According to various embodiments, light-field image data may be processed so as to prevent, remove, and/or mitigate artifacts caused by previous processing steps. A light-field image may first be captured by a light-field camera. One or more processing steps may be applied to the light-field image to generate a processed light-field image having one or more artifacts. A flat white modulation light-field image may also be captured by the light-field camera. The same processing steps previously applied to the light-field image may be applied to the modulation light-field image to generate a processed modulation light-field image with the same artifacts. The artifacts may then be identified in the processed modulation light-field image to generate an identification of the artifacts. This identification may be used to identify the same artifacts in the processed light-field image, which may then be corrected to remove the artifacts to generate a corrected, processed light-field image.
