Re-targeting of multi-script document images for handheld devices

Abstract

We propose here a technique for transforming the layout of a printed document image to a new user-conducive layout. Its objective is to effectuate better display in a low-resolution screen for providing comfort and convenience to a viewer while reading. The task of re-targeting starts with analyzing the document image in the spatial domain for identifying its paragraphs. Text lines, words, characters, and hyphenations are then recognized from each paragraph, and necessary word stitching is performed to reproduce the paragraph, as appropriate to the resolution of the display device. Test results and related subjective evaluation for different datasets, especially the pages scanned from some Bengali and English magazines, demonstrate the strength and effectiveness of the proposed technique.
