Types

type OpponentValues

type OpponentValues struct {

	// red vs. green (long vs. medium)
	RedGreen float32

	// blue vs. yellow (short vs. avg(long, medium))
	BlueYellow float32

	// greyscale luminance channel -- typically use L* from LAB as best
	Grey float32
}

OpponentValues holds color opponent values based on cone-like L,M,S inputs These values are useful for generating inputs to vision models that simulate color opponency representations in the brain.

func NewOpponentValues

func NewOpponentValues(l, m, s, lm, grey float32) OpponentValues

NewOpponentValues returns a new OpponentValues from values representing the LMS long, medium, short cone responses, and an overall grey value.

type Opponents

type Opponents int32 //enums:enum

Opponents enumerates the three primary opponency channels: WhiteBlack, RedGreen, and BlueYellow using colloquial "everyday" terms.

const (
	// White vs. Black greyscale
	WhiteBlack Opponents = iota

	// Red vs. Green
	RedGreen

	// Blue vs. Yellow
	BlueYellow
)

const OpponentsN Opponents = 3

OpponentsN is the highest valid value for type Opponents, plus one.

func OpponentsValues

func OpponentsValues() []Opponents

OpponentsValues returns all possible values for the type Opponents.

func (Opponents) Desc

func (i Opponents) Desc() string

Desc returns the description of the Opponents value.

func (Opponents) Int64

func (i Opponents) Int64() int64

Int64 returns the Opponents value as an int64.

func (Opponents) MarshalText

func (i Opponents) MarshalText() ([]byte, error)

MarshalText implements the encoding.TextMarshaler interface.

func (*Opponents) SetInt64

func (i *Opponents) SetInt64(in int64)

SetInt64 sets the Opponents value from an int64.

func (*Opponents) SetString

func (i *Opponents) SetString(s string) error

SetString sets the Opponents value from its string representation, and returns an error if the string is invalid.

func (Opponents) String

func (i Opponents) String() string

String returns the string representation of this Opponents value.
