Braille Document Image Mosaicing: A Novel Approach

Abstract

Mosaic is an area of art, where small pieces of glass are assembled in a systematic way to get a decorative image. Glasses of different colors are used in mosaic art. In Digital image processing, image mosaicing is the technique of assembling multiple pieces of images to get the combined image. This can be applied on document image or on general image. It is the art of creating big image with congregation of small images. There are many situations where it is not possible to capture large documents with the given imaging media such as digital camera, scanner or copying machines in a single stretch. This results in capture of a large document in terms of split components of a document image. Hence there is a need for mosaicing. Digital Image Mosaicing requires overlapping region to generate a single and complete image. Braille is the language used by visually impaired community for read and write communication. Conventional Mosaicing approach applied on document images fail to work on Braille documents. In this paper, we present a novel and efficient approach to mosaic two split pieces of Braille document.
