ABSTRACT:
An automatic character cell determining apparatus automatically determines the character cells within the text image of a document. A connected component generating means generates connected components from the pixels comprising the text image. A bounding box generating means generates a bounding box surrounding each connected component. A character cell determining means for locating character cells comprising one or more connected components comprises a vertical splaying means and a horizontal splaying means for ensuring white spaces between lines and connected components, a vertical profile means for determining the vertical positions of a line, means for splitting ligatures of two or more connected components and means for generating character cells grouping together one or more connected components.
