Find a FootprintSet given an Image and a threshold.
peakSchema
is used to preserving the input peak schema when merging FootprintSets.
img | Image to search for objects |
threshold | threshold to find objects |
npixMin | minimum number of pixels in an object |

lsst::afw::detection::FootprintSet::FootprintSet | ( | image::Mask< MaskPixelT > const & | img, |
Threshold const & | threshold, | ||
int const | npixMin = 1 ) |
Find a FootprintSet given a Mask and a threshold.
img | Image to search for objects |
threshold | threshold to find objects |
npixMin | minimum number of pixels in an object |
lsst::afw::detection::FootprintSet::FootprintSet | ( | image::MaskedImage< ImagePixelT, MaskPixelT > const & | img, |
Threshold const & | threshold, | ||
std::string const & | planeName = "", | ||
int const | npixMin = 1, | ||
bool const | setPeaks = true ) |
Find a FootprintSet given a MaskedImage and a threshold.
Go through an image, finding sets of connected pixels above threshold and assembling them into Footprints; the resulting set of objects is returned
If threshold.getPolarity() is true, pixels above the Threshold are assembled into Footprints; if it's false, then pixels below Threshold are processed (Threshold will probably have to be below the background level for this to make sense, e.g. for difference imaging)
