remove_noise

remove_noise($inpath,$outpath,$kernel_size=3); - убрать шум с картинки доступна с версии 7.0.56

Функция на вход принимает параметры:

$inpath – путь к исходной картинки (может быть относительным)

$outpath – путь к новой картинке (может быть относительным)

$kernel_size – размер ядра Гауса

После отработки функция возвращает результат своей работы в скрипт :

true – успешно выполнили (boolean)

false – операция не произведена (boolean)
