Detailed Description

The Base Class for Column-wise Filters

This is the base class for linear or non-linear filters that process columns of 2D arrays. Such filters are used for the "vertical" filtering parts in separable filters.

Several functions in OpenCV return Ptr<BaseColumnFilter> for the specific types of filters, and those pointers can be used directly or within cv::FilterEngine.

Unlike cv::BaseRowFilter, cv::BaseColumnFilter may have some context information, i.e. box filter keeps the sliding sum of elements. To reset the state BaseColumnFilter::reset() must be called (e.g. the method is called by cv::FilterEngine)

Constructor & Destructor Documentation

§ BaseColumnFilter()

cv::BaseColumnFilter::BaseColumnFilter ( )

the default constructor

§ ~BaseColumnFilter()

virtual cv::BaseColumnFilter::~BaseColumnFilter ( )

virtual

the destructor

Member Function Documentation

§ operator()()

virtual void cv::BaseColumnFilter::operator()	(	const uchar **	src,
		uchar *	dst,
		int	dststep,
		int	dstcount,
		int	width
	)

pure virtual

the filtering operator. Must be overridden in the derived classes. The vertical border interpolation is done outside of the class.

§ reset()

virtual void cv::BaseColumnFilter::reset ( )

virtual

resets the internal buffers, if any
