# nvRemap
using cuda to do image remapping. many image processing tasks can be done by remapping the image, for example
- flip
- rotate
- scale
- crop
- perspective transform
- lens distortion correction
and so on. And this tasks ca be combined into single remapping kernel, see [transformation composition](https://en.wikipedia.org/wiki/Transformation_matrix#Composing_and_inverting_transformations)
# install
`pip install nvremap`
or build from source
```
git clone https://github.com/ArtificialNotImbecile/nvRemap
cd nvRemap
python setup.py install
```
# usage
see [examples](https://github.com/ArtificialNotImbecile/nvRemap/tree/main/examples)
# TODO
- [ ] add more examples
- [ ] add transform composition
- [ ] add more interpolation methods, currently only support bilinear interpolation
