Download Free/Trial Version Of DespeckleHelper
Despeckle is the process of removing speckles from images (especially bitmaps created using a scanner). Speckles areartifacts which are extra pixels (or collections of extra pixels) that can occur in scanned images because of imperfections in the scannerhardware, or because of dust or dirt being present on the camera, scanning surface or even the document being scanned.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)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 despeckleare inefficient if the correction fails.DespeckleHelper provides a successful method for automatically improving the quality of document images and a marked decrease in OCRerror 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 computationaleffort of the OCR process itself.DespeckleHelper expects as input a monochrome image.
