Forms often contain preprinted elements as field rakes (or combs) or character rakes (or combs). Scanned document in somecases, also have horizontal or vertical lines due to the banding or folding of papers. Dealing with those artifacts is a challenging task for asystem that tries to detect rakes during processing business documents.The document structure analysis and character recognition are usually done in several phases:scanningthresholdingskew detection and correctiondespeckle or speckle removalline removalborder removaldetection of preprinted elements (like boxes or rakes)page orientation detection and correctionlayout analysisclassificationcharacter recognitionEach step must be completed well enough for the performance of the sequence and result to be successful. Steps that follow the rakeremoval 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 stepof form identification and recognition as anchor elements.RakeHelper expects as input a monochrome image.
