bool buildPyramid(const mrpt::img::CImage &img, const size_t nOctaves, const bool smooth_halves=true, const bool convert_grayscale=false)
Fills the vector images with the different octaves built from the input image.
bool buildPyramidFast(mrpt::img::CImage &img, const size_t nOctaves, const bool smooth_halves=true, const bool convert_grayscale=false)
Exactly like buildPyramid(), but if the input image has not to be converted from RGB to grayscale,...
