@spec clear(t()) :: :ok | {:error, String.t()}

Clears the algorithm state

Positional Arguments
  • self: Evision.CalibrateDebevec.t()

Python prototype (for reference only):

clear() -> None
@spec empty(t()) :: boolean() | {:error, String.t()}

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

Positional Arguments
  • self: Evision.CalibrateDebevec.t()
Return

getLambda() -> retval
@spec getRandom(t()) :: boolean() | {:error, String.t()}

getRandom

Positional Arguments
  • self: Evision.CalibrateDebevec.t()
Return
  • retval: bool

Python prototype (for reference only):

getRandom() -> retval
@spec getSamples(t()) :: integer() | {:error, String.t()}
