tfa.image.transform_ops.flat_transforms_to_matrices

View source on GitHub

Converts 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).
name The name for the op.

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.
