tf.keras.ops.fft2

Computes the 2D Fast Fourier Transform along the last two axes of input.

tf.keras.ops.fft2(
    x
)

x Tuple of the real and imaginary parts of the input tensor. Both tensors in the tuple should be of floating type.

A tuple containing two tensors - the real and imaginary parts of the output.

Example:

x = (
    keras.ops.convert_to_tensor([[1., 2.], [2., 1.]]),
    keras.ops.convert_to_tensor([[0., 1.], [1., 0.]]),
)
fft2(x)
(array([[ 6.,  0.],
    [ 0., -2.]], dtype=float32), array([[ 2.,  0.],
    [ 0., -2.]], dtype=float32))
