Abstract:
1. A method of color trapping in an image, the method comprising: identifying, in an image, a color edge having (i) a first side and (ii) a second side; identifying (i) a first pixel on the first side of the color edge and (ii) a second pixel on the second side of the color edge, wherein (i) the first pixel has a first intensity and (ii) the second pixel has a second intensity, and wherein the first pixel and the second pixel are neighboring pixels; and trapping in the first pixel if either (i) the first intensity is greater than the second intensity or (ii) the difference between the first intensity and the second intensity is within a specified threshold, wherein trapping in the first pixel comprises scaling a possible trapping amount by a composite scaling parameter, and wherein the composite scaling parameter is based at least in part on one or more of:
