PerformSuperpixelSLICO

This function picks the maximum value of color distance as compact factor M. So there is no need to input a constant value of M and S. There are two advantages:

[1] The algorithm now better handles both textured and non-textured regions [2] There is not need to set any parameters!!!

SLICO (or SLIC Zero) dynamically varies only the compactness factor, not the step size S.
