Abstract
An automatic script determining apparatus automatically determines the gross script-type of 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 centroid determining means determines a centroid for each bounding box. A script feature determining means determines the locations, relative to the centroid, of one or more predetermined types of features, for each bounding box. A script determining means determines a distribution of the located script features for the entire text image, and compares the determined spatial distribution to predetermined distribution for at least one script-type to determine the script type of the text image.
