public BinaryLabelContourFinderChang2004()

Method Details

process

public void process(GrayU8 binary,
 GrayS32 labeled)

Description copied from interface: BinaryLabelContourFinder

Processes the binary image to find the contour of and label blobs.

Specified by:

process in interface BinaryLabelContourFinder

Parameters:

binary - Input binary image. Not modified.

labeled - Output. Labeled image. Modified.

getContours

public List<ContourPacked> getContours()

Description copied from interface: BinaryContourInterface

Returns a list of contours/blobs found. WARNING: List is recycled on the next call to process().

Specified by:

getContours in interface BinaryContourInterface

Returns:

List of contours.

loadContour

public void loadContour(int contourID,
 DogArray<Point2D_I32> storage)

Description copied from interface: BinaryContourInterface

Used to load the pixels associated with a contour.

Specified by:

loadContour in interface BinaryContourInterface

Parameters:

contourID - ID of the contour you wish to load

storage - Storage for the contour points. Must be set to declare new elements.

writeContour

public void writeContour(int contourID,
 List<Point2D_I32> list)

Description copied from interface: BinaryContourInterface

Overwrites the coordinates of the saved contour. Useful when points have been undistorted and you're trying to minimize memory by not saving another copy

Specified by:

writeContour in interface BinaryContourInterface

Parameters:

contourID - ID of the contour you wish to load

list - Storage for the contour points. Must be set to declare new elements.

setSaveInnerContour

public void setSaveInnerContour(boolean enabled)

Description copied from interface: BinaryContourInterface

Used to toggle on and off the saving of inner contours.

Specified by:

setSaveInnerContour in interface BinaryContourInterface

Parameters:

enabled - true to enable or false to disable

isSaveInternalContours

public boolean isSaveInternalContours()

Specified by:

isSaveInternalContours in interface BinaryContourInterface

setMinContour

public void setMinContour(ConfigLength length)

Description copied from interface: BinaryContourInterface

Specifies the minimum contour as either an absolute value in pixels or a value relative to the sqrt(width*height). Threshold ≤ 0 will be treated as infinite.

Specified by:

setMinContour in interface BinaryContourInterface

getMinContour

public ConfigLength getMinContour(@Nullable
 @Nullable ConfigLength length)

Description copied from interface: BinaryContourInterface

Returns the minimum contour

Specified by:

getMinContour in interface BinaryContourInterface

Parameters:

length - Optional storage for the contour's length

Returns:

The contour's length

setMaxContour

public void setMaxContour(ConfigLength length)

Description copied from interface: BinaryContourInterface

Specifies the maximum contour as either an absolute value in pixels or a value relative to the sqrt(width*height). Threshold ≤ 0 will be treated as infinite.

Specified by:

setMaxContour in interface BinaryContourInterface

getMaxContour

public ConfigLength getMaxContour(@Nullable
 @Nullable ConfigLength length)

Description copied from interface: BinaryContourInterface

Returns the maximum contour. Threshold %le; 0 will be treated as infinite.

Specified by:

getMaxContour in interface BinaryContourInterface

Parameters:

length - Optional storage for the contour's length

Returns:

The contour's length

setConnectRule

public void setConnectRule(ConnectRule rule)

Specified by:

setConnectRule in interface BinaryContourInterface

getConnectRule

public ConnectRule getConnectRule()

Specified by:

getConnectRule in interface BinaryContourInterface
