Function Documentation

template<class T> Image<T> blurAndDecY (  const Image< T > &  src, const int  factor )

Blur and then decimate in Y. Equivalent to decY(sepFilter(src)). This is logically equivalent to constructing a boxcar filter of size factor, then doing decY(sepFilter(src, [], filter)). However, this implementation is optimized to be much faster, especially if factor is large, since we avoid computing the filter results that would just be thrown away by the subsequent decimation.
