LibOPF is a library of functions and programs for free usage in the design of optimum-path forest (OPF) classifiers. This second version has additional features related with the previous one, and it contains the programs related to the supervised classifier reported in [1] and the unsupervised one addressed in [2].
If you intend to compare the supervised OPF classifier with others in the literature, you need to pay attention to our measure of accuracy (see Section 1.1.1).
