kernels.maximum

kernels.maximum(arr, *, validate=True)

Return the NaN-aware maximum along the stack axis.

Parameters

arr : (ndarray, shape(N, *spatial))

Image stack. Accepted dtypes are uint8, uint16, int16, int32, float32, and float64. Integer inputs are promoted to the package’s floating workspace when validate is True. Inputs with more than 3 dimensions are flattened internally; output shapes match the trailing spatial dimensions of the input.

validate : bool = True

If True, check dimensionality and normalize dtype/contiguity before entering the Rust kernel. If False, callers must provide inputs that satisfy the compiled kernel assumptions.

Returns

maximum : (ndarray, shape(*spatial))

Per-pixel maximum of finite values. All-NaN output elements return NaN.
