# Cutout拡張

{% hint style="info" %}
Cutout Augmentation は Enhanced Augmentation の一種で、 **premium** 機能です。

最新のプランとそれに関連する機能については、 [pricing page](https://roboflow.com/pricing).
{% endhint %}

Cutout は画像の一部を黒いボックスでランダムに置き換えます。cutout を追加すると、モデルが物体のオクルージョンに対してより強くなります。

{% hint style="danger" %}
多くの最新モデルは、トレーニング中にオンライン Augmentation として Cutout を適用します。これを 2 回適用すると、望ましくない結果になる可能性があります。Roboflow 3.0 または YOLOv8 でこれを使用することは推奨しません。
{% endhint %}
