Initial Code 
UMat umat = new UMat();

    byte* end = buffer + umat.Bytes.Length;

    for (byte* pointer = buffer; pointer != end; pointer++)

    mostCommonValue = (byte)Array.IndexOf(counters, counters.Max());

Given a UMat we sometimes need to find the most common value in that UMat. This code does it the unsafe (fast) way.
