名称

gray_dilation_rectgray_dilation_rectGrayDilationRectGrayDilationRectgray_dilation_rect — Determine the maximum gray value within a rectangle.

参数签名

gray_dilation_rect(Image : ImageMax : MaskHeight, MaskWidth : )

描述

gray_dilation_rectgray_dilation_rectGrayDilationRectGrayDilationRectGrayDilationRectgray_dilation_rect calculates the maximum gray value of the input image ImageImageImageImageimageimage within a rectangular mask of size (MaskHeightMaskHeightMaskHeightMaskHeightmaskHeightmask_height, MaskWidthMaskWidthMaskWidthMaskWidthmaskWidthmask_width) for each image point. The resulting image is returned in ImageMaxImageMaxImageMaxImageMaximageMaximage_max. If the parameters MaskHeightMaskHeightMaskHeightMaskHeightmaskHeightmask_height or MaskWidthMaskWidthMaskWidthMaskWidthmaskWidthmask_width are even, they are changed to the next larger odd value. At the border of the image the gray values are mirrored.

注意

Note that filter operators may return unexpected results if an image with a reduced domain is used as input. Please refer to the chapter 过滤器.

参数表

ImageImageImageImageimageimage (input_object) (multichannel-)image(-array) → object (byte / direction / cyclic / uint2 / int2 / int4 / real)

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

ImageMaxImageMaxImageMaxImageMaximageMaximage_max (output_object) (multichannel-)image(-array) → object (byte / direction / cyclic / uint2 / int2 / int4 / real)

Image containing the maximum gray values.

MaskHeightMaskHeightMaskHeightMaskHeightmaskHeightmask_height (input_control) extent.y → (integer)

Height of the filter mask.

Default: 11

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

Value range: 3 ≤ MaskHeight MaskHeight MaskHeight MaskHeight maskHeight mask_height ≤ 511

Minimum increment: 2

Recommended increment: 2

Restriction: odd(MaskHeight) && MaskHeight < height(Image) * 2

MaskWidthMaskWidthMaskWidthMaskWidthmaskWidthmask_width (input_control) extent.x → (integer)

Width of the filter mask.

Default: 11

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

Value range: 3 ≤ MaskWidth MaskWidth MaskWidth MaskWidth maskWidth mask_width ≤ 511

Minimum increment: 2

Recommended increment: 2

Restriction: odd(MaskWidth) && MaskWidth < width(Image) * 2

结果

gray_dilation_rectgray_dilation_rectGrayDilationRectGrayDilationRectGrayDilationRectgray_dilation_rect 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>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>). If necessary, an exception is raised.
