## 4/14/2020 Update

We here release ASLFeat with post-CVPR update, which we find to perform consistently better among the evaluations. The model can be accessed by:

```bash
wget https://research.altizure.com/data/aslfeat_models/aslfeatv2.tar
```
We here release ASLFeat with post-CVPR update, which we find to perform consistently better among the evaluations. The model can be accessed from [URL](https://1drv.ms/u/s!Anl8gFgW1C7LkmyOSQXNmBrhq0V-?e=vNXeqt).

On HPatches dataset, the MMA@3 is improved from 72.29 to 74.31 in single scale prediction, while the multi-scale prediction now achieves 75.26. The major difference comes from 1) using blended images and rendered depths, which is proposed in [BlendedMVS](https://github.com/YoYo000/BlendedMVS) and integrated in [GL3D](https://github.com/lzx551402/GL3D), 2) using [circle loss](https://arxiv.org/abs/2002.10857) and 3) conducting early stopping. Details can be found in the updated arxiv paper. The above implementation is also available in [TFMatch](https://github.com/lzx551402/tfmatch).

The extracted features will be stored in ``FM-Bench/Features_aslfeat``. Use Matlab to run ``Pipeline/Pipeline_Demo.m"`` then ``Evaluation/Evaluate.m`` to obtain the results.

The cached results of ASLFeat can be reached [here](https://research.altizure.com/data/aslfeat_models/Results.tar).
