Abstract
A system and method for reducing chromatic aberration by aligning pixel in a color channel according to displacement from corresponding pixels in another color channel. In particular, the system calculates a feature, such as intensity, for a first block of pixels in a first color channel of an image. The feature is calculated for a second block of pixels in a second color channel of the image. Displacement is estimated between the first color channel and the second color channel by comparing the feature for the first block and the feature for the second block. At least a portion of the first color channel is aligned with at least a portion of the second color channel based on the estimated displacement.
