There is a wide variety of statistical models which may be applied to the semantic segmentation tasks. Let us now illustrate their impact on the computation of the label maps. For this purpose we use synthetic Green Field data-set, with 3 classes, described by two features. If we quantize all the features by 8 bit, we can map the whole data set to the 2-dimensional 256 x 256 feature space. If we accumulate the sample points in such representation, it will correspond to the probability densities. For the visualization we will mark these densities, belonging to different classes, with tree different colors: red, green and blue (see Figure below).
