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.
Args:
transform_matrices
: One or more affine transformation matrices, for the reverse transformation in homogeneous coordinates. Shape(3, 3)
or(N, 3, 3)
.
Returns:
2D tensor of flat transforms with shape (N, 8)
, which may be passed into
tf.contrib.image.transform
.
Raises:
ValueError
: Iftransform_matrices
have an invalid shape.
