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)
