# PIV challenge

We put [here](https://foss.heptapod.net/fluiddyn/fluidimage/tree/branch/default/doc/examples/pivchallenge)
scripts to compute PIV on data of the [PIV challenge](http://www.pivchallenge.org).

In the scripts, we use the environment variable
`DIR_DATA_PIV_CHALLENGE` that has to be define in the terminal
with:

```
export DIR_DATA_PIV_CHALLENGE=$HOME/tmp/data
```
