GIMP で編集中の画像を、超解像 AI で綺麗に拡大 / 高画質化 できるようにするプラグイン「gimp_upscale」
<p>今日は、<a href="https://www.gigafree.net/tool/paint/gimp.html" rel="noopener" target="_blank"><strong>GIMP</strong></a> で編集中の画像を、AI の力でアップスケールできるようにするプラグイン<span class="highlight">gimp_upscale</span>を紹介しようと思います。</p>

<p><span id="more-10852"></span></p>
<p>「<strong>gimp_upscale</strong>」は、GIMP 上で超解像 AI を使用できるようにするプラグインです。</p>
<p>GIMP で編集中の画像を、<a href="https://github.com/xinntao/Real-ESRGAN#portable-executable-files-ncnn" rel="noopener" target="_blank">Real-ESRGAN</a> で 0.1 倍 ~ 8 倍にアップスケールできるようにするプラグインで、編集中のレイヤー、もしくは選択した領域内の画像を、AI の力で綺麗に高解像度化(≒高画質化)できるようにしてくれます<sup><b>※1</b></sup>。<br/>
<b>※1</b> <span class="annotate">アップスケール対象を “ レイヤー ” にするとリサイズも行われるが、アップスケール対象を “ 選択領域 ” にすると、対象領域をリサイズすることなく高解像度化(≒高画質化)が行われる。</span></p>
<p>操作は、使用する AI モデルと拡大率を指定するだけなので超簡単。</p>
<p>普段、GIMP を利用している人におすすめです。</p>
