Method Details

getContours

List<ContourPacked> getContours()

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

Returns:

List of contours.

loadContour

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

Used to load the pixels associated with a contour.

Parameters:

contourID - ID of the contour you wish to load

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

writeContour

void writeContour(int contourID,
 List<Point2D_I32> storage)

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

Parameters:

contourID - ID of the contour you wish to load

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

setSaveInnerContour

void setSaveInnerContour(boolean enabled)

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

Parameters:

enabled - true to enable or false to disable

isSaveInternalContours

boolean isSaveInternalContours()

setMinContour

void setMinContour(ConfigLength length)

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.

getMinContour

ConfigLength getMinContour(@Nullable
 @Nullable ConfigLength length)

Returns the minimum contour

Parameters:

length - Optional storage for the contour's length

Returns:

The contour's length

setMaxContour

void setMaxContour(ConfigLength length)

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.

getMaxContour

ConfigLength getMaxContour(@Nullable
 @Nullable ConfigLength length)

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

Parameters:

length - Optional storage for the contour's length

Returns:

The contour's length

setConnectRule

void setConnectRule(ConnectRule rule)

getConnectRule

ConnectRule getConnectRule()

copyContour

static List<Point2D_I32> copyContour(BinaryContourInterface finder,
 int contourID)

Convenience function which loads a contour and creates copy of all the points and returns a new list

Returns:

New copy of contour
