focal.focal_mean(a: Array, *, window: int | tuple[int, ...] | list[int] | ndarray[tuple[int, ...], bool] | Window, fraction_accepted: float = 0.7, verbose: bool = False, reduce: bool = False, chunks: int | tuple[int, int] | None = None, error: Literal['bootstrap', 'parametric'] | None = None, bootstrap_config: BootstrapConfig | None = None, out: MeanResult | None = None) MeanResult

Focal mean

Parameters:
  • a (Array) – Input array to compute the focal mean on. Must be two-dimensional.

  • window (int, array-like, or Window) –

    Window applied over the input array. It can be:

    • An integer (interpreted as a square window),

    • A sequence of integers (interpreted as a rectangular window),

    • A boolean array,

    • Or a pyspatialstats.windows.Window object.

  • fraction_accepted (float, optional) –

    Fraction of valid (non-NaN) cells per window required for computation.

    • 0: all views are used if at least 1 value is present

    • 1: only fully valid views are used

    • Between 0 and 1: minimum fraction of valid cells required

    Default is 0.7.

  • verbose (bool, optional) – If True, print progress message with timing. Default is False.

  • reduce (bool, optional) – If True, uses each pixel exactly once without overlapping windows. The resulting array shape is a_shape / window_shape. Default is False.

  • chunks (int or tuple of int, optional) – Shape of chunks to split the array into. If None, the array is not split into chunks, which is the default.

  • error ({'parametric', 'bootstrap'}, optional) – Error type to compute. If None, no error is computed, which is the default.

  • bootstrap_config (BootstrapConfig, optional) – Bootstrap configuration object.

  • out (MeanResult, optional) – MeanResult object to update in-place

Returns:

Dataclass containing the focal mean array and (optionally) uncertainty measures.

Return type:

MeanResult
