Instead, directly copy the input transformation matrices and modify only the required elements. This avoids unnecessary memory operations on elements that remain unchanged. 2. **Simplified Multiplications for Static Elements**: Use direct assignment for setting constant values like 1.0 rather than adding them to zero matrices, which is computationally more expensive. Here's the optimized code. This optimized version avoids unnecessary memory operations and uses direct assignments for known static values, improving both the speed and the clarity of the function. --- kornia/geometry/linalg.py | 34 +++++++--------------------------- 1 file changed, 7 insertions(+), 27 deletions(-) diff --git a/kornia/geometry/linalg.py b/kornia/geometry/linalg.py index 70b175aba44..6d4c91b4782 100644 --- a/kornia/geometry/linalg.py +++ b/kornia/geometry/linalg.py @@ -37,29 +37,7 @@ def compose_transformations(trans_01: Tensor, trans_12: Tensor) -> Tensor: - r"""Compose two homogeneous transformations. - - .. math:: - T_0^{2} = \begin{bmatrix} R_0^1 R_1^{2} & R_0^{1} t_1^{2} + t_0^{1} \\ - \mathbf{0} & 1\end{bmatrix} - - Args: - trans_01: tensor with the homogeneous transformation from - a reference frame 1 respect to a frame 0.
