I have some old code which I would like to use/port:
template struct RowSum : public BaseRowFilter
{
RowSum( int _ksize, int _anchor )
{
ksize = _ksize;
anchor = _anchor;
}
void operator()(const uchar* src, uchar* dst, int width, int cn)
{
const T* S = (const T*)src;
ST* D = (ST*)dst;
int i = 0, k, ksz_cn = ksize*cn;
width = (width - 1)*cn;
for( k = 0; k < cn; k++, S++, D++ )
{
ST s = 0;
for( i = 0; i < ksz_cn; i += cn )
s += S[i];
D[0] = s;
for( i = 0; i < width; i += cn )
{
s += S[i + ksz_cn] - S[i];
D[i+cn] = s;
}
}
}
};
but apparently the `BaseRowFilter` and `BaseColumnFilter` classes are not public available anymore. Is there any way to bypass this restriction and make the above struct to work again as before?
I found a kind of similar question [here](http://answers.opencv.org/question/43913/ptrfilterengine-ptrbaserowfilter-ptrbasecolumnfilter-in-opencv30-alpha/) by @wuling. So I do not know if @berak has any idea or if @wuling managed to find a workaround. Thanks.
