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.
