Abstract
A method of synthesizing color data through the use of what is called a Gradient Vector Synthesis method is comprised of calculating gradients at 0°, 45°, 90°, and 135° with respect to a generation point in a matrix of color data. A first-level edge test is performed by comparing each of the gradients to a noise threshold. If the first-level test indicates that an edge may be present along either of the diagonals, a second-level test may be performed. An interpolation technique is selected in response to the first-level edge test and, when performed, the second-level edge test. The selected interpolation technique is used to synthesize the missing color data at the generation point.
