Detailed Description

Class implementing the locally uniform comparison image descriptor, described in [316].

An image descriptor that can be computed very fast, while being about as robust as, for example, SURF or BRIEF.

Note
It requires a color image as input.

Member Function Documentation

◆ create()

static Ptr<LUCID> cv::xfeatures2d::LUCID::create ( const int  lucid_kernel = 1,
const int  blur_kernel = 2 
)
static
Python:
cv.xfeatures2d.LUCID.create([, lucid_kernel[, blur_kernel]]) -> retval
cv.xfeatures2d.LUCID_create([, lucid_kernel[, blur_kernel]]) -> retval
Parameters
lucid_kernelkernel for descriptor construction, where 1=3x3, 2=5x5, 3=7x7 and so forth
blur_kernelkernel for blurring image prior to descriptor construction, where 1=3x3, 2=5x5, 3=7x7 and so forth

◆ getBlurKernel()

virtual int cv::xfeatures2d::LUCID::getBlurKernel ( ) const
pure virtual
Python:
cv.xfeatures2d.LUCID.getBlurKernel() -> retval

◆ getDefaultName()

String cv::xfeatures2d::LUCID::getDefaultName ( ) const
virtual
Python:
cv.xfeatures2d.LUCID.getDefaultName() -> retval

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.

Reimplemented from cv::Feature2D.

◆ getLucidKernel()

virtual int cv::xfeatures2d::LUCID::getLucidKernel ( ) const
pure virtual
Python:
cv.xfeatures2d.LUCID.getLucidKernel() -> retval

◆ setBlurKernel()

virtual void cv::xfeatures2d::LUCID::setBlurKernel ( int  blur_kernel)
pure virtual
Python:
cv.xfeatures2d.LUCID.setBlurKernel(blur_kernel) -> None

◆ setLucidKernel()

virtual void cv::xfeatures2d::LUCID::setLucidKernel ( int  lucid_kernel)
pure virtual
Python:
cv.xfeatures2d.LUCID.setLucidKernel(lucid_kernel) -> None
