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 +- s = (i + s) - transpose(s) ,
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.
Input image.
Structuring element.
Gray-closed image.
gray_closing returns 2 (H_MSG_TRUE) if the structuring element is not the empty region. Otherwise, an exception is raised.
