I’ve released several works that experiment with different ways of showing the body’s contours, but none of them have been very popular.
Still, I actually quite like this kind of work.

これまでも身体の動きの差分抽出とか、輪郭抽出なんかの処理をして、いくつかの見せ方を試したのだけれど、どれもあまり高評価ではなかった。
少しだけでもカッコ良くしたいのだけれど、でたらめに踊るにしてもよろけているし、なんだかな。

You can try it out for yourself by adjusting various parameters on a PC or smartphone with a camera.

I added the MOTION EXTRACTION feature to a video I posted a few hours ago, which applies visual effects from a video I posted previously.
This effect extracts the edges of the video, highlights their movement in red, and then gradually fades them out.
Also, in the post from a few hours ago, I had set the audio to stereo—with sounds from my right arm coming from the right and sounds from my left arm coming from the left—but since I accidentally recorded it in mono, I made sure to record it properly in stereo this time.

前回の投稿が素人ヲタ芸おじさんの動画になってしまったので、映像にエフェクトをかけるようにしてみた。 エフェクト自体は昨年投稿したものと同じで、エッジ抽出、動き抽出し、それを徐々にフェードアウトさせるようにしたもの。
数時間前の投稿はステレオ作品をモノラルで録音してしまったので、今回はちゃんとステレオで録音した。右腕の音は右から、左腕の音は左から鳴るようになっています。

Give it a try on a PC with a camera or a smartphone.

Since your arms become bows, try plucking the string with them!
The higher you go along the line, the higher the pitch; the lower you go, the lower the pitch. This would never be possible on a real stringed instrument.
I wish I could have danced more stylishly, but in the end, I just ended up looking like a rowdy, drunk otaku guy. ;p

弦楽器をどう表すかが悩ましくて、現実の楽器ではありえないのだけれど、一本の線の上のほうが高い音で、下のほうは低い音が鳴ります。
どっちみち、正しい音程なんて身体精度的にも映像処理精度的にも無理なので激しく鳴らそうと思ったら、ヲタ芸みたくなってしまった。
イイ歳したおっさんが恥ずかしい……。

Just like before, this is a VST3 plugin that triggers a hi-hat in response to sound. I can switch between open and closed hi-hats by adjusting how wide you open your mouth.
I posted a video of this project a little while ago, but since the camera’s performance was poor, I bought a camera that supports 60 fps and reshot the footage.
I purchased the “EMEET SmartCam C960 Ultra,” which supports 60 fps. In practice, even when I set the resolution to the lowest setting, the frame rate remained around 50 fps, but the response speed improved slightly.
Instead of open and closed hi-hats, you can also trigger bass drum and snare drum sounds.

少し前に投稿した動画で、カメラ性能がボトルネックになって反応速度が悪かったのでちょっと良い60fps対応カメラを買ってみた。
でも、実際にはどれだけ解像度を下げても50fpsが限界だった。他のカメラでも同様かもしれないけれど、騙された感。
少しは反応が良くはなったけれども。
USB3.0以降対応の120fps対応カメラが欲しくなるなあ。
