RakeHelper - Forms often contain preprinted elements as field rakes (or combs) or character rakes (or combs). Scanned document in some cases, also have horizontal or vertical lines due to the banding or folding of papers. Dealing with those artifacts is a challenging task for a system that tries to detect rakes during processing business documents.
The document structure analysis and character recognition are usually done in several phases:
scanning
thresholding
skew detection and correction
despeckle or speckle removal
line removal
border removal
detection of preprinted elements (like boxes or rakes)
page orientation detection and correction
layout analysis
classification
character recognition
Each step must be completed well enough for the performance of the sequence and result to be successful. Steps that follow the rake removal are inefficient if the correction fails.
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.
BordersHelper 1.0 BordersHelper uses an algorithm based on Flood Fill, Component Labelling, and Region Adjacency Graphs. It removes noisy borders in monochromatic images of documents introduced by the digitalization process using automatically fed scanners. BordersHelper expects as input a monochrome image.
BoxesHelper 1.0 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. BoxesHelper expects as input a monochrome image.
LandscapeHelper 1.0 LandscapeHelper detects landscape pages (rotated with 90 degrees) and automatically put the image into the right position for further processing steps (character recognition).
LinesHelper 1.0 LinesHelper finds and removes horizontal and vertical lines and repairs overlapping text and graphics on binary images. The line removal filter can also be configured to reconstruct horizontal and vertical lines, redrawing them straight with smooth edges.
ZoneHelper 1.0 ZoneHelper detects and automatically converts inverted text zones and change white-on-black text to normal black-on-white text.
DespeckleHelper 1.0 DespeckleHelper provides a successful method for automatically improving the quality of document images and a marked decrease in OCR error rates. The method is easy to use - we view it as a pre-OCR cleanup operation, and it takes a very small amount of the computational effort of the OCR process itself. DespeckleHelper expects as input a monochrome image
DeskewHelper 1.0 DeskewHelper allows automatic skew detection and correction. The steps used to deskew an image are: Calculate the slope of the document Compute the rotation angle Calculate the size of a new image large enough to hold the rotated image Allocate the new image Rotate the entire image
