示例1: buildPyramid_templ
void buildPyramid_templ(
CImagePyramid &obj,
mrpt::utils::CImage &img,
const size_t nOctaves,
const bool smooth_halves,
const bool convert_grayscale)
{
ASSERT_ABOVE_(nOctaves,0)
//TImageSize img_size = img.getSize();
obj.images.resize(nOctaves);
// First octave: Just copy the image:
if (convert_grayscale && img.isColor())
{
// In this case we have to convert to grayscale, so FASTLOAD doesn't really matter:
img.grayscale(obj.images[0]);
}
else
{
// No need to convert to grayscale OR image already is grayscale:
if (FASTLOAD)
obj.images[0].copyFastFrom(img); // Fast copy -> "move", destroying source.
else obj.images[0] = img; // Normal copy
}
// Rest of octaves, if any:
for (size_t o=1;o<nOctaves;o++)
{
if (smooth_halves)
obj.images[o-1].scaleHalfSmooth(obj.images[o]);
else obj.images[o-1].scaleHalf(obj.images[o]);
}
