gray_closing ( Image, SE : ImageClosing : : )

Perform a gray value closing on an image.

gray_closing applies a gray value closing to the input image Image with the structuring element SE. The gray value closing of an image i with a structuring element s is defined as

  i +- s = (i + s) - s ,
i.e., a dilation of the image with s followed by an erosion with s (see gray_dilation and gray_erosion). For the generation of structuring elements, see read_gray_se.


Parameters

Image (input_object)
image(-array) -> object : byte / real
Input image.

SE (input_object)
image -> object : byte
Structuring element.

ImageClosing (output_object)
image(-array) -> object : byte / real
Gray-closed image.


Result

gray_closing returns 2 (H_MSG_TRUE) if the structuring element is not the empty region. Otherwise, an exception is raised.

gray_closing is reentrant and automatically parallelized (on tuple level).
