loadFromFile

CustomMap & CortidQCT::ColorToLabelMaps::CustomMap::loadFromFile

(

std::string const &

filename

)

Loads the custom map from a YAML file.

Parameters

filename

Path to the yaml file

Returns

Reference to the loaded map

Exceptions

template<class Label , class Scalar >

Label CortidQCT::ColorToLabelMaps::CustomMap::operator() ( Scalar  red, Scalar  green, Scalar  blue  ) const

inline

Converts a RGB color to a label using the pre-defined lookup table.

Template Parameters

Scalar	scalar type of the color components (floating point)
Label	label type, must be constructible from std::unit64_t

Parameters

red	red compnent in range [0, 1]
green	green component in range [0, 1]
blue	blue component in range [0, 1]

Returns

Label value from the lookup table. If no matching entry can be found in the table, undefinedLabel is returned.

Member Data Documentation

Table CortidQCT::ColorToLabelMaps::CustomMap::table

Initial value:

= {{{{255, 0, 0}}, 0},   {{{0, 255, 0}}, 1},
                 {{{255, 255, 0}}, 2}, {{{0, 0, 255}}, 3},
                 {{{255, 0, 255}}, 4}, {{{0, 255, 255}}, 5}}

mapping table

Maps RGB colors to labels. Defautl value maps the colors red, green, yellow, green, magenta, cyan to 0, 1, 2, 3, 4, 5, respectively.

LabelType CortidQCT::ColorToLabelMaps::CustomMap::undefinedLabel {0}

The label that is returned when no matching entry in the table can be found
