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. |
