How to use percentage in AnalyzeJobDocument

Here we will describe what the percentage in the "AnalyzeJobDocument" means;

Example;

CODE
<AnalyzeJobDocument xmlns="http://xml.vidispine.com/schema/vidispine">
  <black>
    <threshold>0.1</threshold>
    <percentage>95</percentage>
  </black>
  <freeze>
    <time>1.0</time>
    <threshold>0.05</threshold>
  </freeze>
  <bars>
    <percentage>10</percentage>
    <threshold>0.05</threshold>
  </bars>
</AnalyzeJobDocument>

It means that for a particular frame in the video to be marked as blank, 95% of the frame must have a light value less than 0.1 (0: all black, 1: all white).

For bars, it compares all pixels in the frame against a "perfect bar picture", and the number of pixels that differs with more than 0.05 has to be below 10%.
