gray_closing_rectgray_closing_rectgray_closing_rectGrayClosingRectGrayClosingRect (Operator)

Name

gray_closing_rectgray_closing_rectgray_closing_rectGrayClosingRectGrayClosingRect — Perform a gray value closing with a rectangular mask.

Signature

Description

gray_closing_rectgray_closing_rectgray_closing_rectGrayClosingRectGrayClosingRect applies a gray value closing to the input image ImageImageImageImageimage with a rectangular mask of size (MaskHeightMaskHeightMaskHeightMaskHeightmaskHeight, MaskWidthMaskWidthMaskWidthMaskWidthmaskWidth). The resulting image is returned in ImageClosingImageClosingImageClosingImageClosingimageClosing. If the parameters MaskHeightMaskHeightMaskHeightMaskHeightmaskHeight or MaskWidthMaskWidthMaskWidthMaskWidthmaskWidth are even, they are changed to the next larger odd value. At the border of the image the gray values are mirrored.

The gray value closing of an image i with a rectangular 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_rectgray_dilation_rectgray_dilation_rectGrayDilationRectGrayDilationRect and gray_erosion_rectgray_erosion_rectgray_erosion_rectGrayErosionRectGrayErosionRect).

Parameters

Result

gray_closing_rectgray_closing_rectgray_closing_rectGrayClosingRectGrayClosingRect returns 2 (H_MSG_TRUE) if all parameters are correct. If the input is empty the behavior can be set via set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>). If necessary, an exception is raised.
