Detailed Description

Parameters for the detectMarker process:

• int adaptiveThreshWinSizeMin : minimum window size for adaptive thresholding before finding contours (default 23).
• int adaptiveThreshWinSizeMax : maximum window size for adaptive thresholding before finding contours (default 153).
• int adaptiveThreshWinSizeStep : increments from adaptiveThreshWinSizeMin to adaptiveThreshWinSizeMax during the thresholding (default 16).
• double adaptiveThreshConstant : constant for adaptive thresholding before finding contours (default 7)
• double minContoursAreaRate : determine minimum area for marker contour to be detected. This is defined as a rate respect to the area of the input image. Used only if neural network is used (default 0.003).
• double minContoursArea : determine minimum area for marker contour to be detected. This is defined as the actual area. Used only if neural network is not used (default 100).
• double confidenceThreshold : minimum confidence for a bounding box detected by neural network to classify as detection.(default 0.5) (0<=confidenceThreshold<=1)
• double minContourSolidity : minimum solidity of a contour for it be detected as a square in the chart. (default 0.9).
• double findCandidatesApproxPolyDPEpsMultiplier : multipler to be used in cv::ApproxPolyDP function (default 0.05)
• int borderWidth : width of the padding used to pass the inital neural network detection in the succeeding system.(default 0)
• float B0factor : distance between two neighbours squares of the same chart. Defined as the ratio between distance and large dimension of square (default 1.25)
• float maxError : maximum allowed error in the detection of a chart. default(0.1)
• int minContourPointsAllowed : minium points in a detected contour. default(4)
• int minContourLengthAllowed : minimum length of a countour. default(100)
• int minInterContourDistance : minimum distance between two contours. default(100)
• int minInterCheckerDistance : minimum distance between two checkers. default(10000)
• int minImageSize : minimum size of the smaller dimension of the image. default(1000)
• unsigned minGroupSize : minimum number of a squared of a chart that must be detected. default(4)
