Abstract
Methods and apparatus for dynamic correction of data for non-uniformity are disclosed. Feature data are extracted from input video data that include a subject shot against a backing area in a solid color. The feature data may describe characteristics of non-uniformity in input video data. A curve is generated based on the extracted feature data, and correction factors are formed based on the generated curve. At least one of the input video data and alpha data associated with the input video data is corrected based on the correction factors.
