`SLEPLET` is a Python package for the construction of Slepian wavelets in the
spherical and manifold (via meshes) settings. The API of `SLEPLET` has been
designed in an object-orientated manner and is easily extendible. Upon
installation, `SLEPLET` comes with two command line interfaces - `sphere` and
`mesh` - which allows one to easily generate plots on the sphere and a set of
meshes using `plotly`.
To read more about Slepian wavelets please see the following publications
[](https://dx.doi.org/10.1109/LSP.2021.3050961)
[](https://dx.doi.org/10.1109/TSP.2022.3233309)
[](https://doi.org/10.48550/arXiv.2302.06006)
[](https://paddyroddy.github.io/thesis)
## Installation
The recommended way to install `SLEPLET` is via
[pip](https://pypi.org/project/pip)
```sh
pip install sleplet
```
To install the latest development version of `SLEPLET` clone this repository
and run
```sh
pip install -e .
```
This will install two scripts `sphere` and `mesh` which can be used to generate
the figures in
[the associated papers](https://astro-informatics.github.io/sleplet#paper-figures).
### Supported Platforms
`SLEPLET` has been tested with
[](https://www.python.org).
Windows is not currently supported as `SLEPLET` relies on
[pyssht](https://pypi.org/project/pyssht) and
[pys2let](https://pypi.org/project/pys2let) which do not work on Windows.
These can hopefully be replaced with
[s2fft](https://github.com/astro-informatics/s2fft) and
[s2wav](https://github.com/astro-informatics/s2wav) in the future when they
are available on [PyPI](https://pypi.org).
## Example Usage
`SLEPLET` may be interacted with via the API or the CLIs.
### API Usage
The following demonstrates the first wavelet (ignoring the scaling function) of
the South America region on the sphere.
```python
import sleplet
B, J, J_MIN, L = 3, 0, 2, 128
region = sleplet.slepian.Region(mask_name="south_america")
f = sleplet.functions.SlepianWavelets(L, region=region, B=B, j_min=J_MIN, j=J)
f_sphere = sleplet.slepian_methods.slepian_inverse(f.coefficients, f.L, f.slepian)
sleplet.plotting.PlotSphere(
f_sphere,
f.L,
f"slepian_wavelets_south_america_{B}B_{J_MIN}jmin_{J_MIN+J}j_L{L}",
normalise=False,
region=f.region,
).execute()
```
### CLI Usage
The demonstrates the first wavelet (ignoring the scaling function) of the head
region of a Homer Simpson mesh for a per-vertex normals field.
```sh
mesh homer -e 3 2 0 -m slepian_wavelet_coefficients -u -z
```
## Documentation
See here for the [documentation](https://astro-informatics.github.io/sleplet).
This includes demonstrations of the figures from the associated papers along
with the API documentation. Further examples are included in the
[examples folder](https://github.com/astro-informatics/sleplet/tree/main/examples).
