 右上がイラストA、左上がイラストBのうち使われている色をヒストグラフに取ったものとし、RGの色分布とする。
 イラストAのRGの色が特に密集しているところの色を、イラストBの色が密集しているところに移動する処理を実装したい。
 
 つまりイラストBの色使いでイラストAの色を塗りなおすという感じ。
 
 ただ今アルゴリズム思考中。
 結構古典的な処理だと思うので、調べればなにか見つかると思うのだけど?
 減色処理との違いは、色を移動するだけなので、色数自体を減らしたいわけじゃないという点。
 
 適当でいいなら難しくはなさそうだけど、手順が少しめんどくさそう。
 
 普遍的な処理法があるなら、それでいきたいけど、そちらは少し難しそう?
 
 
 
 
 *1 XY軸をRGに、RGの使われている回数をZ軸にとれば色のヒストグラフを取れば山並のようなものが見えてくる。
 *2 山の頂に当たるところをサーチすれば島の山頂が見つかる。
 *3 山頂から探索し、一定値以上の場所を探せば島のようなものがでてくるから後は島ごとにらべリング処理をすれば、島がみつかるはず?
 *4  この概念をRGBに拡張すると良い
 
  
 
 上記概念に基づき、作りかけのフィルタを掲載。
 FormにPictureBox2個、ボタン3個 C#で稼動。
 Pixiv登録yamasushiさんにアドバイスをもらって堀江伸一が製作中。
