示例1: Detect
/// <summary>
/// Finds lines in the input image.
/// This is the output of the default parameters of the algorithm on the above shown image.
/// </summary>
/// <param name="image">A grayscale (CV_8UC1) input image. </param>
/// <param name="lines">A vector of Vec4i or Vec4f elements specifying the beginning and ending point of a line.
/// Where Vec4i/Vec4f is (x1, y1, x2, y2), point 1 is the start, point 2 - end. Returned lines are strictly oriented depending on the gradient.</param>
/// <param name="width">Vector of widths of the regions, where the lines are found. E.g. Width of line.</param>
/// <param name="prec">Vector of precisions with which the lines are found.</param>
/// <param name="nfa">Vector containing number of false alarms in the line region,
/// with precision of 10%. The bigger the value, logarithmically better the detection.</param>
