// * Replaces {@link Float#NaN NaN} values by the weighted average of neighbors values. This
// * operation uses a box of {@code size}&times{@code size} pixels centered on each {@code NaN}
// * value, where {@code size} = 2&times;{@code padding}+1 (the <cite>padding</cite> is the number
// * of pixel above, below, to the left and to the right of central {@code NaN} pixel). The weighted
// * average is then computed, ignoring all {@code NaN} values. If the number of valid values is
// * greater than or equals to {@code validityThreshold}, then the center {@code NaN} is replaced by
// * the computed average. Otherwise, the {@code NaN} value is left unchanged.
