Operators

auto dip::operator!=(dip::Measurement::IteratorFeature const& featureValues, dip::Measurement::ValueType value) -> dip::LabelMap
Selects objects where the first element of featureValues is unequal to value.

The + operator merges two dip::Measurement objects. more...
auto dip::operator<(dip::Measurement::IteratorFeature const& featureValues, dip::Measurement::ValueType value) -> dip::LabelMap
Selects objects where the first element of featureValues is smaller than value.
auto dip::operator<<(std::ostream& os, dip::Measurement const& measurement) -> std::ostream&
You can output a dip::Measurement to std::cout or any other stream to produce a human-readable representation of the tabular data in it.
auto dip::operator<=(dip::Measurement::IteratorFeature const& featureValues, dip::Measurement::ValueType value) -> dip::LabelMap
Selects objects where the first element of featureValues is not greater than value.
auto dip::operator==(dip::Measurement::IteratorFeature const& featureValues, dip::Measurement::ValueType value) -> dip::LabelMap
Selects objects where the first element of featureValues is equal to value.
auto dip::operator>(dip::Measurement::IteratorFeature const& featureValues, dip::Measurement::ValueType value) -> dip::LabelMap
Selects objects where the first element of featureValues is greater than value.
auto dip::operator>=(dip::Measurement::IteratorFeature const& featureValues, dip::Measurement::ValueType value) -> dip::LabelMap
