Applies a median filter of rank to a signal.
Rank is right rank if right rank is greater than zero. Rank is left rank if right rank is less than zero.
The input signal to filter.
The number of elements, n, in signal must be greater than right rank. If the number of elements in signal is less than or equal to right rank, the node sets filtered signal to an empty array and returns an error.
The number of elements used to compute the median filter to the left side.
left rank must be greater than or equal to 0.
The number of elements used to compute the median filter to the right side.
If right rank is less than 0, the node assumes right rank is equal to left rank. right rank must be less than signal.
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
Error information. The node produces this output according to standard error behavior.
This node obtains the elements of filtered signal using the following equation.
The following equation describes Ji.
where rl is the filter left rank, and rr is the filter right rank.
The following illustration shows the computation of Yi.
