Detailed Description

Class implementing the locally uniform comparison image descriptor, described in [235].

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:
	retval	=	cv.xfeatures2d.LUCID_create(	[, lucid_kernel[, blur_kernel]]	)

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
