tf.contrib.image.flat_transforms_to_matrices(transforms)
Defined in tensorflow/contrib/image/python/ops/image_ops.py
.
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.
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
: Iftransforms
have an invalid shape.
