pure virtual |
Finds line segments in a binary image using the probabilistic Hough transform.
src | 8-bit, single-channel binary source image. |
lines | Output vector of lines. Each line is represented by a 4-element vector \((x_1, y_1, x_2, y_2)\) , where \((x_1,y_1)\) and \((x_2, y_2)\) are the ending points of each detected line segment. |
stream | Stream for the asynchronous version. |
