Constructors

CudaHoughSegmentDetector(float, float, int, int, int)

Create a hough segment detector

public CudaHoughSegmentDetector(float rho, float theta, int minLineLength, int maxLineGap, int maxLines = 4096)

Parameters

rho float

Distance resolution of the accumulator in pixels.

theta float

Angle resolution of the accumulator in radians.

minLineLength int

Minimum line length. Line segments shorter than that are rejected.

maxLineGap int

Maximum allowed gap between points on the same line to link them.

maxLines int

Maximum number of output lines.

Methods

Detect(IInputArray, IOutputArray, Stream)

Finds line segments in a binary image using the probabilistic Hough transform.

public void Detect(IInputArray image, IOutputArray lines, Stream stream = null)

Parameters

image IInputArray

8-bit, single-channel binary source image

lines IOutputArray

Output vector of lines. Each line is represented by a 4-element vector (x1, y1, x2, y2) , where (x1, y1) and (x2, y2) are the ending points of each detected line segment.

stream Stream

Use a Stream to call the function asynchronously (non-blocking) or null to call the function synchronously (blocking).

DisposeObject()

Release the unmanaged memory associated with this segment detector
