cvHoughLinesP

Basic

Module: OpenCV

Finds lines segments in a binary image using probabilistic Hough transform.

Name Type Range Description
Input value inImage Image UINT8, single-channel input image.
Input value inRho Real 0.1 - Distance resolution of the accumulator in pixels.
Input value inTheta Real 0.1 - Angle resolution of the accumulator in degrees.
Input value inThreshold Integer 1 - Accumulator threshold parameter.
Input value inMinLineLength Real Minimum line length. Line segments shorter than that are rejected.
Input value inMaxLineGap Real Maximum allowed gap between points on the same line to link them.
Output value outLines Segment2DArray Output array of segments.
