◆ detect() [1/2]

void cv::line_descriptor::LSDDetector::detect ( const Mat image,
std::vector< KeyLine > &  keypoints,
int  scale,
int  numOctaves,
const Mat mask = Mat() 
)
Python:
cv.line_descriptor.LSDDetector.detect(image, scale, numOctaves[, mask]) -> keypoints
cv.line_descriptor.LSDDetector.detect(images, keylines, scale, numOctaves[, masks]) -> None

Detect lines inside an image.

Parameters
imageinput image
keypointsvector that will store extracted lines for one or more images
scalescale factor used in pyramids generation
numOctavesnumber of octaves inside pyramid
maskmask matrix to detect only KeyLines of interest

◆ detect() [2/2]

void cv::line_descriptor::LSDDetector::detect ( const std::vector< Mat > &  images,
std::vector< std::vector< KeyLine > > &  keylines,
int  scale,
int  numOctaves,
const std::vector< Mat > &  masks = std::vector< Mat >() 
) const
Python:
cv.line_descriptor.LSDDetector.detect(image, scale, numOctaves[, mask]) -> keypoints
cv.line_descriptor.LSDDetector.detect(images, keylines, scale, numOctaves[, masks]) -> None

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters
imagesinput images
keylinesset of vectors that will store extracted lines for one or more images
scalescale factor used in pyramids generation
numOctavesnumber of octaves inside pyramid
masksvector of mask matrices to detect only KeyLines of interest from each input image
