LSDDetector()#

cv::line_descriptor::LSDDetector::LSDDetector()

Python:

cv.line_descriptor.LSDDetector(_params) -> <line_descriptor_LSDDetector object>

Member Function Documentation#

detect()#

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])

Detect lines inside an image.

Parameters

image — input image
keypoints — vector that will store extracted lines for one or more images
scale — scale factor used in pyramids generation
numOctaves — number of octaves inside pyramid
mask — mask matrix to detect only KeyLines of interest

detect()#

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 >() )

Python:

cv.line_descriptor.LSDDetector.detect(image, scale, numOctaves[, mask]) -> keypoints

cv.line_descriptor.LSDDetector.detect(images, keylines, scale, numOctaves[, masks])

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

Parameters

images — input images
keylines — set of vectors that will store extracted lines for one or more images
scale — scale factor used in pyramids generation
numOctaves — number of octaves inside pyramid
masks — vector of mask matrices to detect only KeyLines of interest from each input image
