java.lang.Object javax.media.jai.OperationDescriptorImpl javax.media.jai.operator.IDCTDescriptor
An OperationDescriptor
describing the "IDCT" operation.
The "IDCT" operation computes the inverse even discrete cosine transform (DCT) of an image. Each band of the destination image is derived by performing a two-dimensional inverse DCT on the corresponding band of the source image.
