# Noise Augmentation

画像にランダムなソルト＆ペッパーノイズを加え、カメラ由来のアーティファクトに対してモデルをより堅牢にします。

* Percent: 影響を受ける画像のピクセルの割合を選択します。最大25％です。

## 例

<figure><img src="/files/b28b4f64a40941f3068ccf4a605d2b34d56af56e" alt=""><figcaption><p>元画像</p></figcaption></figure>

<figure><img src="/files/d9a168519914f542e3cb6252cb46de04c1406927" alt=""><figcaption><p>ノイズ Augmentation が .3% に設定されています</p></figcaption></figure>
