Binarizer class abstract
This class hierarchy provides a set of methods to convert luminance data to 1 bit data.
It allows the algorithm to vary polymorphically, for example allowing a very expensive thresholding technique for servers and a fast one for mobile. It also permits the implementation to vary, e.g. a JNI version for Android and a Java fallback version for other platforms.
