ランダム ノイズによる自動生成アート画像。

コマンドライン インターフェイスの素晴らしき画像操作アプリケーション ソフトウェアである “ImageMagick” にてカラフルな模様を自動生成致しました。

パターンは上下左右が繋がっているので、タイル状に並べても継ぎ目が出来ません。
Perlin noise (パーリン ノイズ)的なパターンの応用です。

簡単に言うと、半径が2^0から2^7までのガウス暈しを適用したランダム ノイズの複数のレイヤーを合成して生成したものです。

何百枚でも連続自動生成出来ますが、1枚生成するのに多少の時間が掛かります。
ImageMagickの “-clone, +clone, -delete, +delete” などを使用して処理を効率化しています。

暈し半径を大きくすると、16bit/チャンネルの精度で処理していても、色の境界線が誤差により不自然にギザギザしてしまいますので、半径32画素以上の暈しは、半径32画素分のガウス暈しを複数回適用して処理しております。

今回生成した数十枚の画像を、超解像AIの人工ニューラル ネットワークに食べさせます。

“ImageMagick” の使用方法の解説ウェブサイト:
http://www.imagemagick.org/Usage/

画像を生成する為のLinuxのコマンドを掲載致します。
ImageMagickはQ16 (内部16bit精度)ヴァージョンを事前にインストールして置いて下さい。
mkdirで作業ディレクトリーに “images” というフォルダーを作成し、そこへ生成画像を連番で保存するようになっております。
以下の全文をコピーして “端末” にペーストすると16枚の1024 x 1024画素の画像の生成を開始します。
