Description
if (Pixel_Persistence_Count(Previous_Pixel) = Maximum_Persistence(X)
or
New_Pixe≠0
or
Previous_Pixel = 0)
then
Pixel_Persistence_Count(Resulting_Pixel) = 0
and
Resulting_Pixel = New_Pixel
else
Pixel_Persistence_Count(Resulting_Pixel) = Pixel_Persistence_Count(Previous_Pixel) + 1
and
Resulting_Pixel = Previous_Pixel
すなわち、
前のピクセルのピクセル・パーシステンス計数値が最大のパーシステンスXならば、
又は
新たなピクセル値が0でなければ、
又は
前のピクセル値が0ならば、
その場合は、
結果ピクセルのピクセル・パーシステンス計数値が0となり、
且つ
結果ピクセルが新たなピクセルとなる。
そうでなければ、
結果ピクセルのピクセル・パーシステンス計数値が前のピクセルのピクセル・パーシステンス計数値に+1した値となり、
且つ
結果ピクセルが前のピクセルとなる(即ち、ピクセル値が変化しない)。
