cvGeneralizedHoughBallard_Initialization

Basic

Module: OpenCV

Finds arbitrary template in the grayscale image using Generalized Hough Transform.

Name Type Description
Input value inPattern Image
Input value inPatternCenter Point2D*
Input value inCannyHighThreshold Integer*
Input value inCannyLowThreshold Integer*
Input value inDp Double* Inverse ratio of the accumulator resolution to the image resolution.
Input value inMaxBufferSize Integer*
Input value inMinDistance Double* Minimum distance between the centers of the detected objects
Input value inLevels Integer* Feature table levels.
Input value inVotesThreshold Integer* The accumulator threshold for the template centers at the detection stage. The smaller it is, the more false positions may be detected.
Output value outBallard CvGeneralizedHoughBallard

Requirements

For input inPattern only pixel formats are supported: 1⨯uint8.
