/**
* Class implementing the SEEDS (Superpixels Extracted via Energy-Driven Sampling) superpixels
* algorithm described in CITE: VBRV14 .
*
* The algorithm uses an efficient hill-climbing algorithm to optimize the superpixels' energy
* function that is based on color histograms and a boundary term, which is optional. The energy
* function encourages superpixels to be of the same color, and if the boundary term is activated, the
* superpixels have smooth boundaries and are of similar shape. In practice it starts from a regular
* grid of superpixels and moves the pixels or blocks of pixels at the boundaries to refine the
* solution. The algorithm runs in real-time using a single CPU.
