- All Implemented Interfaces:
- OperationDescriptor, RegistryElementDescriptor, Serializable
- public class ExpDescriptor
- extends OperationDescriptorImpl
An OperationDescriptor describing the "Exp" operation.
The "Exp" operation takes the exponential of the pixel values
of an image. The pixel values of the destination image are defined
by the pseudocode:
dst[x][y][b] = java.lang.Math.exp(src[x][y][b])
For integral image datatypes, the result will be rounded and clamped
as needed.
