CLASSIFICATION OF TEXT AND GRAPHIC REGIONS ON A FRAGMENT OF DOCUMENT IMAGE
Abstract:

The goal of this paper is to develop a method for the classification of region of document image as graphic or text content type. As an input of the method segment (rectangular region of an image) containing a homogeneous content – text or graphic object – is used. Region analysis is performed on the assumption that it is a text region, ​​projection partition allows to split this region into objects of smaller size. Construction of the narrative function characterizing areas of the image sub-elements is proposed. Feature size distribution for the next processing step is used for training and classification using support vector machines. Using the proposed approach allows to classify text area with a probability of 0.9859, graphics region – with a probability of about 0.9451. An investigation of the drawbacks and limitations of the proposed method was performed, areas of its applications were discovered. Scientific results of the paper can be used in automatic document image processing, analysis and pattern recognition.
