tf.contrib.image.flat_transforms_to_matrices

Converts tf.contrib.image projective transforms to affine matrices.

tf.contrib.image.flat_transforms_to_matrices(
    transforms
)

Note that the output matrices map output coordinates to input coordinates. For the forward transformation matrix, call tf.linalg.inv on the result.

Args
transforms	Vector of length 8, or batches of transforms with shape (N, 8).

Returns
3D tensor of matrices with shape (N, 3, 3). The output matrices map the output coordinates (in homogeneous coordinates) of each transform to the corresponding input coordinates.

Raises
ValueError	If transforms have an invalid shape.
