      エイヴィン・コーロース(Øyvind Kolås)氏が最近開発した「色の同化格子錯視」(color assimilation grid illusion)の技法の説明。氏と全く同じアルゴリズムになっているかどうは保証の限りではないが。まずはグレースケール画像。pic.twitter.com/rV87IGkYcr

      グレースケール画像に、元のカラー画像の色の情報を集めた縞を載せると、出来上がり。灰色の部分も色づいて見える。「色の同化」って、こういう話だったのですね、という感じ。「色の同化はそんなもんだ」とおっしゃる方もいそうですが、これまでここまで説得力のあるデモはありませんでした。pic.twitter.com/eJp45dPnr6

      ちなみに、色の情報を集めた縞単独で、元の画像をある程度知覚できます。インチキ? いえ、スリット視というものです。「パークスのらくだ」だったかな。いや、あれは運動視が必須だったのかも。pic.twitter.com/aleRetLSIZ

      静止画のスリット視も、結構パワフルです。この画像では、15ピクセルに1ピクセル分しか情報がありませんが、元の画像がある程度わかると思います。pic.twitter.com/jeFXYLBvr9

      30ピクセルごとに1ピクセルの情報でも、少しはどんな画像だったかわかるかも。pic.twitter.com/bchKXvIBfc

      ちなみに、オリジナルの画像はこちらです。ハートが上昇して見える錯視図形のつもりで作成したのですが、「動いて見えない」と言われるので、お蔵入りしていたものを、このほど活用。pic.twitter.com/SUMRgvKRkh
