描述

该算子 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

Note that filter operators may return unexpected results if an image with a reduced domain is used as input. Please refer to the chapter 过滤器.

运行信息

• 多线程类型:可重入(与非独占操作符并行运行)。
• 多线程作用域:全局(可以从任何线程调用)。
• 在元组级别自动并行化。
• 在图像通道级别自动并行化。
• Automatically parallelized on domain level.
