描述

erosion_seqerosion_seqErosionSeqErosionSeqErosionSeqerosion_seq computes the sequential erosion of the input region 区域区域区域区域区域区域 with the selected structuring element GolayElementGolayElementGolayElementGolayElementgolayElementgolay_element from the Golay alphabet. This is done by executing 该算子 erosion_golayerosion_golayErosionGolayErosionGolayErosionGolayerosion_golay with all rotations of the structuring element IterationsIterationsIterationsIterationsiterationsiterations times. The following structuring elements can be selected:

'l', 'd', 'c', 'f', 'h', 'k'.

Only the “foreground elements” (even rotation numbers) are used. The elements 'i' and 'e' result in unchanged output regions. The elements 'l', 'm' and 'f2' are identical for the foreground. The Golay elements, together with all possible rotations, are described with 该算子 golay_elementsgolay_elementsGolayElementsGolayElementsGolayElementsgolay_elements.

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。

Complexity

Let F be the area of an input region. Then the runtime complexity for one region is:

结果

erosion_seqerosion_seqErosionSeqErosionSeqErosionSeqerosion_seq returns 2 ( H_MSG_TRUE) if all parameters are correct. The behavior in case of empty or no input region can be set via:

Otherwise, an exception is raised.
