        <dd>This class implements a local thresholding algorithm, which while slower than the
GlobalHistogramBinarizer, is fairly efficient for what it does. It is designed for
high frequency images of barcodes with black data on white backgrounds. For this application,
it does a much better job than a global blackpoint with severe shadows and gradients.</dd>
