gray_closinggray_closingGrayClosingGrayClosing (Operator)

Name

gray_closinggray_closingGrayClosingGrayClosing — Perform a gray value closing on an image.

Signature

gray_closing(Image, SE : ImageClosing : : )

Herror gray_closing(const Hobject Image, const Hobject SE, Hobject* ImageClosing)

Herror T_gray_closing(const Hobject Image, const Hobject SE, Hobject* ImageClosing)

void GrayClosing(const HObject& Image, const HObject& SE, HObject* ImageClosing)

HImage HImage::GrayClosing(const HImage& SE) const

static void HOperatorSet.GrayClosing(HObject image, HObject SE, out HObject imageClosing)

HImage HImage.GrayClosing(HImage SE)

Description

gray_closinggray_closingGrayClosingGrayClosingGrayClosing applies a gray value closing to the input image ImageImageImageImageimage with the structuring element SESESESESE. The image type of the structuring element SESESESESE must match the image type of the input image ImageImageImageImageimage. 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_dilationgray_dilationGrayDilationGrayDilationGrayDilation and gray_erosiongray_erosionGrayErosionGrayErosionGrayErosion). For the generation of structuring elements, see read_gray_seread_gray_seReadGraySeReadGraySeReadGraySe.

The gray value closing is particularly fast for flat structuring elements, i.e., structuring elements with a constant gray level within their domain.

Execution Information

Parameters

ImageImageImageImageimage (input_object)  (multichannel-)image(-array) objectHImageHImageHobject (byte / uint2 / real)

Input image.

SESESESESE (input_object)  singlechannelimage objectHImageHImageHobject (byte / uint2 / real)

Structuring element.

ImageClosingImageClosingImageClosingImageClosingimageClosing (output_object)  (multichannel-)image(-array) objectHImageHImageHobject * (byte / uint2 / real)

Gray-closed image.

Result

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