OcrEngine engine = new OcrEngine();
// set image
engine.setImage(ImageStream.fromFile(dir + "template.jpg"));
// create collection of filters
CorrectionFilters filters = new CorrectionFilters();
// create & add a few filters to the collection
filters.add(new MedianFilter(6));
filters.add(new GaussBlurFilter());
// assign collection to OcrEngine
