Modifier and Type | Method and Description |
---|---|
FHT |
conjugateMultiply(FHT fht)
Returns the image resulting from the point by point Hartley conjugate
multiplication of this image and the specified image.
|
void |
dfht3(float[] x,
int base,
boolean inverse,
int maxN)
Performs an optimized 1D FHT.
|
FHT |
divide(FHT fht)
Returns the image resulting from the point by point Hartley division
of this image by the specified image.
|
ImageStack |
getComplexTransform()
Converts this FHT to a complex Fourier transform and returns it as a two slice stack.
|
FHT |
getCopy()
Returns a clone of this FHT.
|
ImageProcessor |
getPowerSpectrum()
Returns an 8-bit power spectrum, log-scaled to 1-254.
|
void |
inverseTransform()
Performs an inverse transform, converting this image into the space domain.
|
FHT |
multiply(FHT fht)
Returns the image resulting from the point by point Hartley multiplication
of this image and the specified image.
|
boolean |
powerOf2Size()
Returns true of this FHT contains a square image with a width that is a power of two.
|
void |
rc2DFHT(float[] x,
boolean inverse,
int maxN)
Performs a 2D FHT (Fast Hartley Transform).
|
void |
setShowProgress(boolean showProgress)
Enables/disables display of the progress bar during transforms.
|
void |
swapQuadrants()
Swap quadrants 1 and 3 and 2 and 4 of the image
contained in this FHT.
|
void |
swapQuadrants(ImageProcessor ip)
Swap quadrants 1 and 3 and 2 and 4 of the specified ImageProcessor
so the power spectrum origin is at the center of the image.
|
java.lang.String |
toString()
Returns a string containing information about this FHT.
|
void |
transform()
Performs a forward transform, converting this image into the frequency domain.
