# Miipher demo |
|
This repository provices pretrained weights and demo of Miipher implementation by [Wataru-Nakata](https://github.com/Wataru-Nakata/miipher) |
|
Miipher was originally proposed by Koizumi et. al. [arxiv](https://arxiv.org/abs/2303.01664) |
|
Please note that the model differs in many ways from the paper. |
|
|
|
**Non commercial use only** as the weights are provided in CC-BY-NC 2.0. |
