示例1: gaussBlur
GrayImage gaussBlur(GrayImage const& src, float h_sigma, float v_sigma)
{
using namespace boost::lambda;
if (src.isNull()) {
return src;
}
GrayImage dst(src.size());
gaussBlurGeneric(
src.size(), h_sigma, v_sigma,
src.data(), src.stride(), StaticCastValueConv<float>(),
dst.data(), dst.stride(), _1 = bind<uint8_t>(RoundAndClipValueConv<uint8_t>(), _2)
);
return dst;

std::vector<double>& equations,
std::vector<double>& data_points) const
{
int const width = image.width();
