Detailed Description

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

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

Parameters

lucid_kernel	kernel for descriptor construction, where 1=3x3, 2=5x5, 3=7x7 and so forth
blur_kernel	kernel 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

getDefaultName()

String cv::xfeatures2d::LUCID::getDefaultName ( ) const

virtual

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

setBlurKernel()

virtual void cv::xfeatures2d::LUCID::setBlurKernel ( int  blur_kernel )

pure virtual

setLucidKernel()

virtual void cv::xfeatures2d::LUCID::setLucidKernel ( int  lucid_kernel )

pure virtual
