基本范例  (2)

删除一个二值图像中与图像边界相连通的分量：

Wolfram Language code: DeleteBorderComponents[[image]]

删除与三维图像边界连接的分量：

Wolfram Language code: DeleteBorderComponents[[image]]

范围  (1)

从一个标签矩阵中删除边界分量：

Wolfram Language code: DeleteBorderComponents[ (⁠| | | | | | - | - | - | - | | 0 | 0 | 0 | 0 | | 0 | 1 | 0 | 0 | | 0 | 0 | 0 | 0 | | 0 | 0 | 0 | 2 |⁠)]//MatrixForm

选项  (1)

CornerNeighbors  (1)

默认情况下，假定8-连通度：

Wolfram Language code: DeleteBorderComponents[[image]]

假定 4-连通度以进行分量计算：

Wolfram Language code: DeleteBorderComponents[[image], CornerNeighbors -> False]

应用  (1)

通过周期性填充一个单一模式创建纹理图像：

Wolfram Language code: pattern = [image];
Wolfram Language code: ii = ImageCrop[pattern, {100, 80}, Padding -> "Periodic"]

删除与边界相邻从而不完整的模式：

Wolfram Language code: DeleteBorderComponents[ii]

属性和关系  (2)

当从标签矩阵删除边界分量时，分量不会被重新标记：

Wolfram Language code: DeleteBorderComponents[ (⁠| | | | | | | - | - | - | - | - | | 0 | 0 | 0 | 0 | 1 | | 0 | 2 | 2 | 0 | 0 | | 0 | 0 | 0 | 0 | 3 | | 0 | 4 | 4 | 0 | 0 | | 0 | 0 | 0 | 0 | 5 |⁠)]//MatrixForm

通过掩模边界，然后使用 GeodesicDilation，也可能获取同样的效果：

Wolfram Language code: i = [image]; {w, h} = ImageDimensions[i]; a = ImageMultiply[ImagePad[ConstantImage[Black, {w, h} - 2], 1, White], i] i - GeodesicDilation[a, i]
