Function maximum_filter 

pub fn maximum_filter<T, D>(
    input: &ArrayBase<OwnedRepr<T>, D>,
    size: &[usize],
    mode: Option<BorderMode>,
    origin: Option<&[isize]>,
) -> Result<ArrayBase<OwnedRepr<T>, D>, NdimageError>
where
    T: Float + FromPrimitive + Debug + PartialOrd + Clone + Send + Sync + AddAssign + DivAssign + 'static,
    D: Dimension + 'static,

Apply a maximum filter to an n-dimensional array

A maximum filter replaces each element with the maximum value in its neighborhood.

Arguments

• input - Input array to filter
• size - Size of the filter kernel in each dimension. If a single integer is provided, it will be used for all dimensions.
• mode - Border handling mode (defaults to Reflect)
• origin - Origin of the filter kernel. Default is None, which centers the kernel.

Returns

• Result<Array<T, D>> - Filtered array

Examples

use scirs2_core::ndarray::{Array2, array};
use scirs2_ndimage::filters::{maximum_filter, BorderMode};

let input = array![[1.0, 2.0, 3.0],
                    [4.0, 5.0, 6.0],
                    [7.0, 8.0, 9.0]];

// Apply 3x3 maximum filter
let filtered = maximum_filter(&input, &[3, 3], None, None).expect("Operation failed");
