gray_closing — Perform a gray value closing on an image.
gray_closing(Image, SE : ImageClosing : : )
gray_closing applies a gray value closing to the input image
Image with the structuring element SE. The image
type of the structuring element SE must match the image
type of the input image Image. The gray value closing of
an image i with a structuring element s is defined as
i.e., a dilation of the image with s followed by an erosion with
the transposed structuring element (see gray_dilation and
gray_erosion). For the generation of structuring elements,
see read_gray_se.
The gray value closing is particularly fast for flat structuring elements, i.e., structuring elements with a constant gray level within their domain.
Image (input_object) (multichannel-)image(-array) → object (byte / uint2 / real)
Input image.
SE (input_object) singlechannelimage → object (byte / uint2 / real)
Structuring element.
ImageClosing (output_object) (multichannel-)image(-array) → object (byte / uint2 / real)
Gray-closed image.
gray_closing returns 2 (
H_MSG_TRUE)
if the structuring element is not
the empty region. Otherwise, an exception is raised.
