int WlzValueMedianInt	(	int *	values,

Computes the median of the given vector (the vector's values are overwritten), where the vector type is of int values. The algorithm is based on min-max elimination as used by Peath A W. Median finding on a 3x3 Grid. Graphics Gems, 171-175. Academic Press. 1990. If the vector has less than 1 element 0 is returned. In the trivial case of 1 or 2 elements, the first element's value is returned. If the vector has more than 3 elements:

Returns: Median value.

The given vector is partitioned into two portions: the 1st having ((n + 1) / 2) + 1 elements.
While all the elements have not been examined:
- Find maximum and minimum values in the 1st
- Replace the min value with the first in the partition and the max with the last in the partition.
- Replace the first value in the first partition with the next value from the second partition.
- Reduce the length of the first partion by 1, ie omit the last value.
This leaves 3 values in the 1st partion, their median is found by direct comparison.

Parameters

values	Vector of int values.
nVal	Number of values in vector.
