[ About ]
ネットでRGBずらしという記事からインスピレーションを受けて（パクって）、openFrameworks + OpenCVを使って似たような事をしてみました。

記事の中では静止画でしたが、動画でチャレンジです。
最初はUSBカメラからリアルタイムにやって見たんだけど、絵力がなかったので、ネットのフリー素材動画を拝借しました。

全体でRGBをずらすと目に悪そうなものが出来上がったので、フレームでずらしました。
そのため、動いている部分だけRGBがずれる形になります。

なぜかOpenCVのMatイメージとofImageを同期させるのは前からよくやっていた手法なんですが、今回は何故かopenFrameworksで表示される画像が青味がかったものになったので、OpenCVで表示してます。
(そのため使っているのは実質、OpenCVだけです)
