描述

算子 monotonymonotonyMonotonyMonotonyMonotonymonotony calculates the monotony operator. Thereby the points which are strictly smaller than the current gray value will be counted in the 8 neighborhood. This number will be entered into the output imaged.

If there is a strict maximum, the value 8 is returned; in case of a minimum or a plateau, the value 0 will be returned. A ridge or a slope will return the corresponding intermediate values.

The monotony operator is often used to prepare matching operations as it is invariant with regard to lightness modifications.

注意

请注意，若使用域缩减后的图像作为输入，滤波器算子可能会返回意外结果。请参阅 滤波器 一章
