描述

erosion_seqerosion_seqErosionSeqErosionSeqErosionSeqerosion_seq computes the sequential erosion of the input region RegionRegionRegionRegionregionregion with the selected structuring element GolayElementGolayElementGolayElementGolayElementgolayElementgolay_element from the Golay alphabet. This is done by executing the operator 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 the operator golay_elementsgolay_elementsGolayElementsGolayElementsGolayElementsgolay_elements

复杂度

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

结果

erosion_seqerosion_seqErosionSeqErosionSeqErosionSeqerosion_seq 在所有参数正确时返回 2 ( H_MSG_TRUE )。当输入区域为空或不存在时,其行为可通过以下方式设置:

否则,将抛出异常。
