作成したプログラムには欠陥がある。今回の課題ではない1度ずつ探索を行いその中でも最もスコアが高かった時の角度を最後の出力しているが、自分が想定した角度とは違う角度が最大となっている例として画像2-2では自分は最適な角度が0度であると考えているのに対して、出力では最適な角度は----と自分が想定している角度ではなかった。このようになった理由として考えられるのはキティの特徴の考え方の一つであると思われる黄色の目と鼻の位置が元からある場所よりも近いのがあったからと考えられる。また画像2-2や2-3であった複数のキティを検出だが検出することはできたものの最終出力では複数の赤枠の出力ができなかった。2ー3のファイルでは画像を回転させるごとにキティを探索することができたが(60、180、300)このプログラムでは最もテンプレートに近い時のキティである
