Contact text detection in scanned images
Abstract:
A device and method for identifying text pixels that are erroneously classified as non-text pixels, includes accessing an image region containing a non-text component. For each non-text component within the image region component, only one determines if there are any long line structures within the bounding box defined by the non-text component. If the long line structures are greater than a predefined percentage of the span of the dimension of the bounding box parallel to the line structure, then the line structure is removed. Any remaining non-text pixels within the bounding box are reclassified as text-pixels.
