gray_tophatgray_tophatGrayTophatgray_tophatGrayTophatGrayTophat — Perform a gray value top hat transformation on an image.
gray_tophatgray_tophatGrayTophatgray_tophatGrayTophatGrayTophat applies a gray value top hat transformation to
the input image ImageImageImageImageImageimage with the structuring element
SESESESESESE. The image type of the structuring element SESESESESESE
must match the image type of the input image ImageImageImageImageImageimage. The
gray value top hat transformation of an image i with a structuring
element s is defined as
i.e., the difference of the image and its opening with s (see
gray_openinggray_openingGrayOpeninggray_openingGrayOpeningGrayOpening). For the generation of structuring elements,
see read_gray_seread_gray_seReadGraySeread_gray_seReadGraySeReadGraySe.
The top hat transformation is particularly fast for flat structuring
elements, i.e. structuring elements with a constant gray level
within their domain.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.
- Automatically parallelized on channel level.
- Automatically parallelized on internal data level.
gray_tophatgray_tophatGrayTophatgray_tophatGrayTophatGrayTophat returns 2 (H_MSG_TRUE) if the structuring element is not
the empty region. Otherwise, an exception is raised.
