Description

gray_erosion_rectgray_erosion_rectGrayErosionRectgray_erosion_rectGrayErosionRectGrayErosionRect calculates the minimum gray value of the input image ImageImageImageImageImageimage within a rectangular mask of size (MaskHeightMaskHeightMaskHeightMaskHeightMaskHeightmaskHeight, MaskWidthMaskWidthMaskWidthMaskWidthMaskWidthmaskWidth) for each image point. The resulting image is returned in ImageMinImageMinImageMinImageMinImageMinimageMin. If the parameters MaskHeightMaskHeightMaskHeightMaskHeightMaskHeightmaskHeight or MaskWidthMaskWidthMaskWidthMaskWidthMaskWidthmaskWidth are even, they are changed to the next larger odd value. At the border of the image the gray values are mirrored.

Parameters

ImageImageImageImageImageimage (input_object)  (multichannel-)image(-array) objectHImageHImageHImageHImageXHobject (byte / direction / cyclic / uint2 / int2 / int4 / real)

Image for which the minimum gray values are to be calculated.

ImageMinImageMinImageMinImageMinImageMinimageMin (output_object)  (multichannel-)image(-array) objectHImageHImageHImageHImageXHobject * (byte / direction / cyclic / uint2 / int2 / int4 / real)

Image containing the minimum gray values.

MaskHeightMaskHeightMaskHeightMaskHeightMaskHeightmaskHeight (input_control)  extent.y HTupleHTupleHTupleVARIANTHtuple (integer) (int / long) (Hlong) (Hlong) (Hlong) (Hlong)

Height of the filter mask.

Default value: 11

Suggested values: 3, 5, 7, 9, 11, 13, 15

Typical range of values: 3 ≤ MaskHeight MaskHeight MaskHeight MaskHeight MaskHeight maskHeight ≤ 511 (lin)

Minimum increment: 2

Recommended increment: 2

Restriction: odd(MaskHeight)

Result

gray_erosion_rectgray_erosion_rectGrayErosionRectgray_erosion_rectGrayErosionRectGrayErosionRect 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>)SetSystem("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.
