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