SwisTrack/Components/OutputImageStatisticsBinary

DescriptionEdit

This component calculates and outputs the following statistical values of a binary image:

  • Number of non-zero pixels
  • Sum of all pixels
  • Mean and standard deviation of all pixels
  • Minimum and maximum value among all pixels

Combined with (adaptive) background subtraction, such values are useful to detect sudden changes or out-of-the-ordinary frames in a video stream.
