描述
gen_disc_segen_disc_seGenDiscSeGenDiscSeGenDiscSegen_disc_se generates an ellipsoidal structuring element
(SESESESESEse) for gray morphology of images. The parameter
TypeTypeTypeTypetypetype determines the image type. It must match the image
type of the image to be processed in subsequent operator calls using
this structuring element. The parameters WidthWidthWidthWidthwidthwidth and
HeightHeightHeightHeightheightheight determine the length of the two major axes of the
ellipse. The value of SmaxSmaxSmaxSmaxsmaxsmax determines the maximum gray
value of the structuring element. For the generation of arbitrary
structuring elements, see read_gray_seread_gray_seReadGraySeReadGraySeReadGraySeread_gray_se。The structuring
element can be saved as image with the help of the operator
write_imagewrite_imageWriteImageWriteImageWriteImagewrite_image。However, take care to use an image format that
supports alpha channels to save the shape of the structuring element
such as 'tiff', 'jp2' or 'png'. These files can then be loaded
again with the operator read_imageread_imageReadImageReadImageReadImageread_image。
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
