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

请注意,若使用域缩减后的图像作为输入,滤波器算子可能会返回意外结果。请参阅 滤波器 一章

执行信息

参数

ImageImageImageImageimageimage (输入对象)  (multichannel-)image(-array) objectHImageHObjectHImageHobject (byte / direction / cyclic / uint2 / int2 / int4 / real)

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

ImageMaxImageMaxImageMaxImageMaximageMaximage_max (输出对象)  (multichannel-)image(-array) objectHImageHObjectHImageHobject * (byte / direction / cyclic / uint2 / int2 / int4 / real)

Image containing the maximum gray values.

MaskHeightMaskHeightMaskHeightMaskHeightmaskHeightmask_height (输入控制)  extent.y HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Height of the filter mask.

默认值: 11

建议值: 3, 5, 7, 9, 11, 13, 15

值范围: 3 ≤ MaskHeight MaskHeight MaskHeight MaskHeight maskHeight mask_height ≤ 511

最小增量: 2

建议增量: 2

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

MaskWidthMaskWidthMaskWidthMaskWidthmaskWidthmask_width (输入控制)  extent.x HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Width of the filter mask.

默认值: 11

建议值: 3, 5, 7, 9, 11, 13, 15

值范围: 3 ≤ MaskWidth MaskWidth MaskWidth MaskWidth maskWidth mask_width ≤ 511

最小增量: 2

建议增量: 2

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

结果

gray_dilation_rectgray_dilation_rectGrayDilationRectGrayDilationRectGrayDilationRectgray_dilation_rect 在所有参数正确时返回 2 ( H_MSG_TRUE )。 如果输入为空则可设置行为通过 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>)。如有必要,则抛出异常。
