Base class for lines detector algorithm. :
| 
 | pure virtual | 
Finds lines in a binary image using the classical Hough transform.
| src | 8-bit, single-channel binary source image. | 
| lines | Output vector of lines. Each line is represented by a two-element vector \((\rho, \theta)\) . \(\rho\) is the distance from the coordinate origin \((0,0)\) (top-left corner of the image). \(\theta\) is the line rotation angle in radians ( \(0 \sim \textrm{vertical line}, \pi/2 \sim \textrm{horizontal line}\) ). | 
| stream | Stream for the asynchronous version. | 
| 
 | pure virtual | 
Downloads results from cuda::HoughLinesDetector::detect to host memory.
| d_lines | Result of cuda::HoughLinesDetector::detect . | 
| h_lines | Output host array. | 
| h_votes | Optional output array for line's votes. | 
| stream | Stream for the asynchronous version. |
