Description

closing_rectangle1closing_rectangle1closing_rectangle1ClosingRectangle1ClosingRectangle1 performs a dilation_rectangle1dilation_rectangle1dilation_rectangle1DilationRectangle1DilationRectangle1 followed by an erosion_rectangle1erosion_rectangle1erosion_rectangle1ErosionRectangle1ErosionRectangle1 on the input region RegionRegionRegionRegionregion. The size of the rectangular structuring element is determined by the parameters WidthWidthWidthWidthwidth and HeightHeightHeightHeightheight. As is the case for all closingclosingclosingClosingClosing variants, regions' boundaries are smoothed and holes within a region which are smaller than the rectangular structuring element are closed.

Attention

closing_rectangle1closing_rectangle1closing_rectangle1ClosingRectangle1ClosingRectangle1 is applied to each input region separately. If gaps between different regions are to be closed, union1union1union1Union1Union1 or union2union2union2Union2Union2 has to be called first.

Width of the structuring rectangle.

Default value: 10

Suggested values: 1, 2, 3, 4, 5, 7, 9, 12, 15, 19, 25, 33, 45, 60, 110, 150, 200

Typical range of values: 1 ≤ Width Width Width Width width ≤ 511 (lin)

Minimum increment: 1

Recommended increment: 1

Height of the structuring rectangle.

Default value: 10

Suggested values: 1, 2, 3, 4, 5, 7, 9, 12, 15, 19, 25, 33, 45, 60, 110, 150, 200

Typical range of values: 1 ≤ Height Height Height Height height ≤ 511 (lin)

Complexity

Let F1 be the area of an input region and H be the height of the rectangle. Then the runtime complexity for one region is: 

       O(2 * sqrt(F1) * log2(H)) .

Result

closing_rectangle1closing_rectangle1closing_rectangle1ClosingRectangle1ClosingRectangle1 returns 2 (H_MSG_TRUE) if all parameters are correct. The behavior in case of empty or no input region can be set via:

Otherwise, an exception is raised.
