  80. In a first step, to improve the definition of interest areas and facilitate identification of

  82. binary representation of clustered saliency map, since values of the map can vary according to
  83. the characteristics of frame under analysis, it is not convenient to use a fixed threshold. So,
  84. *Otsu's algorithm* is used, which assumes that the image to be thresholded contains two classes
  85. of pixels or bi-modal histograms (e.g. foreground and back-ground pixels); later on, the
  86. algorithm calculates the optimal threshold separating those two classes, so that their
  87. intra-class variance is minimal.
