skimage.transform.radon(image, theta=None, circle=False)
[source] -
Calculates the radon transform of an image given specified projection angles.
Parameters: image : array_like, dtype=float
Input image. The rotation axis will be located in the pixel with indices
(image.shape[0] // 2, image.shape[1] // 2)
.theta : array_like, dtype=float, optional (default np.arange(180))
Projection angles (in degrees).
circle : boolean, optional
Assume image is zero outside the inscribed circle, making the width of each projection (the first dimension of the sinogram) equal to
min(image.shape)
.Returns: radon_image : ndarray
Radon transform (sinogram). The tomography rotation axis will lie at the pixel index
radon_image.shape[0] // 2
along the 0th dimension ofradon_image
