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

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

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

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.

ValueError If transforms have an invalid shape.
