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

tf.contrib.image.matrices_to_flat_transforms(
    transform_matrices
)

Note that we expect matrices that map output coordinates to input coordinates. To convert forward transformation matrices, call tf.linalg.inv on the matrices and use the result here.

transform_matrices One or more affine transformation matrices, for the reverse transformation in homogeneous coordinates. Shape (3, 3) or (N, 3, 3).

2D tensor of flat transforms with shape (N, 8), which may be passed into tf.contrib.image.transform.

ValueError If transform_matrices have an invalid shape.
