Use image processing to improve the accuracy of OCR.
Create a list of filters that will be applied to the input image in the order you specify.
\code
    filters = new PreprocessingFilter();
    filters.add(PreprocessingFilter.auto_dewarping());
    filters.add(PreprocessingFilter.invert());
    filters.add(PreprocessingFilter.threshold(150));
    filters.add(PreprocessingFilter.binarize());
    filters.add(PreprocessingFilter.rotate(180));
    filters.add(PreprocessingFilter.scale(6));
    filters.add(PreprocessingFilter.dilate());

    images = OcrInput(InputType.PDF, filters);
\endcode
