摘要：This disclosure pertains to novel devices, methods, and computer readablemedia for performing “blind” color defringing on images. In one embodiment, the blinddefringing process begins with blind color edge alignment. This process largely cancelsevery kind of fringe, except for axial chromatic aberration. Next, the process looks at the
edges and computes natural high and low colors to either side of the edge, attemptingto get new pixel colors that aren't contaminated by the fringe color. Next, the processresolves the pixel's estimated new color by interpolating between the low and highcolors, based on the green variation across the edge and the amount of green in the pixelthat is being repaired. Care is taken to prevent artifacts in areas that generally do notfringe, like red-black boundaries and skin tone. Finally, the process computes the finalrepaired color by using luminance-scaling of the new pixel color estimate.
