- All Implemented Interfaces:
- OperationDescriptor, RegistryElementDescriptor, Serializable
- public class DCTDescriptor
- extends OperationDescriptorImpl
An OperationDescriptor
describing the "DCT" operation.
The "DCT" operation computes the even discrete cosine transform
(DCT) of an image. Each band of the destination image is derived by
performing a two-dimensional DCT on the corresponding band of the
source image.
