Typical OCR software can handle only binary images with black pixels representing text and white pixels representing background. It isn't unusual in modern documents to have inverted text zones and normal text zones within the same document.
The document structure analysis and character recognition are usually done in several phases:
skew detection and correction
despeckle or speckle removal
detection of preprinted elements (like boxes)
page orientation detection and correction
character recognition (normal and inverse)
Each step must be completed well enough for the performance of the sequence and result to be successful. ZoneHelper detects and automatically converts inverted text zones and change white-on-black text to normal black-on-white text.
ZoneHelper expects as input a monochrome image.

DespeckleHelper provides a successful method for automatically improving the quality of document images and a marked decrease in OCR error rates.
BoxesHelper searches for boxes the aim being the extraction and recognition of the characters. Also boxes can be used as features in the step of form identification and recognition as anchor elements.

LinesHelper finds and removes horizontal and vertical lines and repairs overlapping text and graphics on binary images.
BordersHelper removes noisy borders in monochromatic images of documents introduced by the digitalization process using automatically fed scanners.
RakeHelper searches for rakes the aim being the extraction and recognition of the characters. Also rakes can be used as features in the step of form identification and recognition as anchor elements.
