 GrayF32 image)

Description copied from interface: DiscreteFourierTransform

Applies the inverse transform to a fourier transformed image to recover the original image

Specified by:

inverse in interface DiscreteFourierTransform<GrayF32,InterleavedF32>

Parameters:

transform - (Input) Fourier transform. twice width and same height of output. Default: Not modified.

image - (Output) reconstructed image. Modified.

setModifyInputs

public void setModifyInputs(boolean modify)

Description copied from interface: DiscreteFourierTransform

This function can toggle the internal implementations ability to modify the input image or input transform.

Specified by:

setModifyInputs in interface DiscreteFourierTransform<GrayF32,InterleavedF32>

Parameters:

modify - true for the input can be modified and false for it will not be modified.

isModifyInputs

public boolean isModifyInputs()

Description copied from interface: DiscreteFourierTransform

Returns state of forward modification flag

Specified by:

isModifyInputs in interface DiscreteFourierTransform<GrayF32,InterleavedF32>

Returns:

true for the input can be modified and false for it will not be modified.
