これ以降に記述されている内容は、このようなコンピューター・プログラムを制作した、というような事を、ただ、述べているに過ぎない。
以下の記述を読んだ人が、それを単に参考にする、というのであれば、問題は無いと、思われる。
しかし、記述されている内容に沿って、その人が、そこに記されているのと同様の制作や作業を行った際に、その制作、作業、コンピューターの作動の結果、使用されたコンピューター等、様々な方面において、何らかの問題が発生しない、という保証は、全くない。
その制作、作業、コンピューターの作動の結果、その人や、その人が所属している組織、その人が使用した様々な機器、インフラストラクチャー等の、身の上にどのような事が起ころうとも、私は一切、責任を負わない。
このプログラムは、Python(パイソン) 言語を使って、記述されている。
－－－－－－－－－－
様々なモジュールの記述において、何らかの画像に関する処理をしたい、というような時に、このモジュールの関数を呼び出して処理することができるように、ということで、これを制作した。
OpenCV2 を使用して、画像処理を行うように、した。
画像に対して、ピクセル単位の処理も、行えるように、した。
エラー処理に関しては、下記のコンテツにに記述したものを利用している。
