• The ForwardDCT Method computes the forward Discrete Cosine Transform (DCT) of the input data.
• The ForwardDCTFromImage Method computes the forward Discrete Cosine Transform (DCT) of the input image. The difference between this method and ForwardDCT is that this method takes an ImGearPage Class as the input. Can be applied only to 8, 16, or 32bit grayscale images with one channel.
