## What is MANUFACIA Image Data Augmentation Tool?

Image data augmentation is a strategy to increase the quantity of image data points for AI training models.
Without collecting new data, this tool increases the number of data points by cropping, rotating, flipping, adding noise, etc., to some of the original data points.
In MANUFACIA, it is often possible to improve the inference accuracy rate by increasing the number of data points for machine learning.


```{important}
Augmented datasets can be only used for training.

## Operating environment

This application was built as a 64 bit application and **will not work on 32 bit OS**.

- Windows10 Home/Pro 64bit
- Linux 64bit (Tested on Ubuntu 18.04 LTS)

## Installation and how to start

### Windows

Copy the ```xc_mat_electron-win32-x64-1.0.0.zip``` to an arbitrary directory and unzip, then start ```xc_mat_electron.exe```.

### Linux (Ubuntu)

Copy the file ```xc_mat_electron-linux-x64.tar.gz``` in home directory and untar it.

```
tar -xvf xc_mat_electron-linux-x64.tar.gz
```

Move into the extracted directory ```xc_mat_electron-linux-x64```.

```
cd xc_mat_electron-linux-x64
```

Execute the binary ```xc_mat_electron```.

```
./xc_mat_electron
```

```{important}
  Without changing the current directory to where the executable file is, the system cannot find other necesary files and it will not work properly.
```
