Method Details

lineRansac

public static <I extends ImageGray<I>>
DetectLineSegment<I> lineRansac(@Nullable
 @Nullable ConfigLineRansac config,
 Class<I> imageType)

Detects line segments inside an image using the DetectLineSegmentsGridRansac algorithm.

Parameters:

config - Configuration for line detector

imageType - Type of single band input image.

Returns:

Line segment detector

houghLineFootSub

public static <T extends ImageGray<T>>
DetectLine<T> houghLineFootSub(@Nullable
 @Nullable ConfigHoughFootSubimage config,
 Class<T> imageType)

Detects lines using a foot of norm parametrization and sub images to reduce degenerate configurations, see DetectLineHoughFootSubimage for details.

Parameters:

config - Configuration for line detector. If null then default will be used.

imageType - input image type

Returns:

Line detector.

houghLineFoot

public static <T extends ImageGray<T>>
DetectLine<T> houghLineFoot(@Nullable
 @Nullable ConfigHoughGradient configHough,
 @Nullable
 @Nullable ConfigParamFoot configParam,
 Class<T> imageType)

Used to find edges along the side of objects. Image gradient is found and thresholded. The pixel coordinate of each active pixel and its gradient is then used to estimate the parameter of a line. Uses HoughTransformGradient with HoughParametersFootOfNorm

Parameters:

configHough - Configuration for hough binary transform.

configParam - Configuration for polar parameters

imageType - type of input image

Returns:

Line detector.

houghLinePolar

public static <T extends ImageGray<T>>
DetectLine<T> houghLinePolar(@Nullable
 @Nullable ConfigHoughGradient configHough,
 @Nullable
 @Nullable ConfigParamPolar configParam,
 Class<T> imageType)

Used to find edges along the side of objects. Image gradient is found and thresholded. The pixel coordinate of each active pixel and its gradient is then used to estimate the parameter of a line. Uses HoughTransformGradient with HoughParametersPolar

Parameters:

configHough - Configuration for hough binary transform.

configParam - Configuration for polar parameters

imageType - type of input image

Returns:

Line detector.

houghLinePolar

public static <T extends ImageGray<T>>
DetectLine<T> houghLinePolar(@Nullable
 @Nullable ConfigHoughBinary configHough,
 @Nullable
 @Nullable ConfigParamPolar configParam,
 Class<T> imageType)

Line detector which converts image into a binary one and assumes every pixel with a value of 1 belongs to a line. Uses HoughTransformBinary with HoughParametersPolar

Parameters:

configHough - Configuration for hough binary transform.

configParam - Configuration for polar parameters

imageType - type of input image

Returns:

Line detector.
