描述

dilation_seqdilation_seqDilationSeqDilationSeqDilationSeqdilation_seq computes the sequential dilation 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 the operator dilation_golaydilation_golayDilationGolayDilationGolayDilationGolaydilation_golay with all rotations of the structuring element IterationsIterationsIterationsIterationsiterationsiterations times. The following structuring elements can be selected:

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

In order to compute the skeleton of a region, usually the elements 'l' and 'm' are used. 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.

运行信息

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Automatically parallelized on tuple level.

Complexity

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

结果

dilation_seqdilation_seqDilationSeqDilationSeqDilationSeqdilation_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.
