Fragment reconstruction aims to restore broken images and documents via matching spatial adjacent fragments. As the existing solutions in the literature still remain problematic, we present a novel feature descriptor, Normal Direction Local Binary Pattern (termed as ND-LBP), for document/image fragment matching. ND-LBP is based on the conventional LBP descriptor, however, it outstands LBP by introducing...
A lossless digital watermarking scheme, which was zero- perturbation on the content and graphics for the digital image maps, is proposed. During the simulation, the scheme has been utilized to model the copyright protection program as a commerce application. Compared to the traditional digital watermarking schemes, our scheme operates in redundancy areas of maps and is scalable to topology changes...
Watermarking appraisement plays an important role in testing the performance of a watermark system. Until now, there is not any comprehensive appraisement method for watermarking algorithms. In this paper, a novel appraisement scheme based on the certainty factor theory is proposed. All of targets or sub-targets which have effect on the performance of watermark are assigned evaluation value to denote...
