| PolarToComplexDescriptor | | public class PolarToComplexDescriptor extends OperationDescriptorImpl (Code) | | An OperationDescriptor describing the "PolarToComplex"
operation.
The "PolarToComplex" operation creates an image with complex-valued
pixels from two images the respective pixel values of which represent the
magnitude (modulus) and phase of the corresponding complex pixel in the
destination image. The source images should have the same number of bands.
The first source image contains the magnitude values and the second source
image the phase values. The destination will have twice as many bands with
the even-indexed bands (0, 2, ...) representing the real and the
odd-indexed bands (1, 3, ...) the imaginary parts of each pixel. The
pixel values of the destination image are defined for a given complex
sample by the pseudocode:
dst[x][y][2*b] = src0[x][y][b]*Math.cos(src1[x][y][b])
dst[x][y][2*b+1] = src0[x][y][b]*Math.sin(src1[x][y][b])
where the index b varies from zero to one less than the number
of bands in the source images.
For phase images with integral data type, it is assumed that the actual
phase angle is scaled from the range [-PI, PI] to the range [0, MAX_VALUE]
where MAX_VALUE is the maximum value of the data type in question.
"PolarToComplex" defines a PropertyGenerator that sets the "COMPLEX"
property of the image to java.lang.Boolean.TRUE, which may
be retrieved by calling the getProperty() method with
"COMPLEX" as the property name.
