Description
gen_disc_segen_disc_seGenDiscSeGenDiscSegen_disc_se generates an ellipsoidal structuring element
(SESESESEse) for gray morphology of images. The parameter
TypeTypeTypetypetype 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 WidthWidthWidthwidthwidth and
HeightHeightHeightheightheight determine the length of the two major axes of the
ellipse. The value of SmaxSmaxSmaxsmaxsmax determines the maximum gray
value of the structuring element. For the generation of arbitrary
structuring elements, see read_gray_seread_gray_seReadGraySeReadGraySeread_gray_se. The structuring
element can be saved as image with the help of the operator
write_imagewrite_imageWriteImageWriteImagewrite_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_imageReadImageReadImageread_image.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
