Typedef Documentation

◆ ConstPeakCatalog

typedef afw::table::CatalogT<PeakRecord const> lsst::afw::detection::ConstPeakCatalog

Definition at line 245 of file Peak.h.

◆ FootprintIdPixel

typedef std::uint64_t lsst::afw::detection::FootprintIdPixel

Pixel type for FootprintSet::insertIntoImage()

This is independent of the template parameters for FootprintSet, and including it within FootprintSet makes it difficult for SWIG to interpret the type.

Definition at line 48 of file FootprintSet.h.

◆ PeakCatalog

typedef afw::table::CatalogT<PeakRecord> lsst::afw::detection::PeakCatalog

Definition at line 244 of file Peak.h.

◆ PeakColumnView

typedef afw::table::ColumnViewT<PeakRecord> lsst::afw::detection::PeakColumnView

Definition at line 243 of file Peak.h.

Function Documentation

◆ createThreshold()

Threshold lsst::afw::detection::createThreshold ( const double  value,
const std::string  type = "value",
const bool  polarity = true 
)

Factory method for creating Threshold objects.

Parameters
valuevalue of threshold
typestring representation of a ThresholdType. This parameter is optional. Allowed values are: "variance", "value", "stdev", "pixel_stdev"
polarityIf true detect positive objects, false for negative
Returns
desired Threshold

Definition at line 109 of file Threshold.cc.
