## 🚀 Feature We would like to have in `kornia.enhance` a batched device agnostic version of the `cv::threshold` including the different variants. Different threshold types: - [ ] THRESH_BINARY -...

squared_distance is quite innecifient used in this way. The funciton itself first compute the norm, then it is squared and now sqrt.... use directly the `norm` here. _Originally posted by...

## 🚀 Feature Deprecate python 3.6 -- support Python >= 3.7 ______________________________________________________________________ #### Consider also to contribute to Kornia universe projects :) - [**Tutorials**](https://github.com/kornia/tutorials): our repository containing the tutorials.

### Describe the bug Only happens with `torch.float32` / `torch.device("cuda")` For `torch.float64` / `torch.device("cuda")` seems fine ```bash > dst_norm_trans_src_norm: torch.Tensor = normalize_homography(M, (H, W), (h_out, w_out)) # Bx3x3 (Pdb) normalize_homography(M,...

## 🚀 Feature Add `Quaternion` class that is compatible with `Eigen::Quaternion` https://eigen.tuxfamily.org/dox/classEigen_1_1Quaternion.html Initial implementation here: https://github.com/kornia/kornia/blob/liegroup-algebra/kornia/geometry/liegroup/quaternion.py ## Motivation We want a simple api that can be easily combined with `kornia.geometry.conversions`...
