Summary:An automatic character cell determining apparatus automatically determines the character cells (Fig. 3) within the text image of a document (Fig. 2). A connected component generating means (28) generates connected components from the pixels comprising the text image. A bounding box generating means (30) generates a bounding box surrounding each connected component. A character cell determining means (38) for locating character cells comprising one or more connected components comprises a vertical splaying means (32) and a horizontal splaying means (360) for ensuring white spaces between lines and connected components, a vertical profile means (34) for determining the vertical positions of a line, means (362) for splitting ligatures of two or more connected components and means for generating character cells grouping together one or more connected components.
