In this work, a reversible watermarking technique is proposed for DICOM (Digital Imaging and Communications in Medicine) image that offers high embedding capacity (payload), security and fidelity of the watermarked image. The goal is achieved by embe

An efficient ITO-free top-illuminated organic photovoltaic (TOPV) based on small molecular planar heterojunction was achieved by spinning a buffer layer of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), on the Ag-AgOx anode. The

This paper proposes a data-hiding scheme for quality access control of digital images using quantization index modulation (QIM) and its hardware implementation. To achieve the goal, an encoded binary message is embedded over N-mutually orthogonal sig

Dither modulation is a well-known data hiding technique for the quality access control of the digital image. Sometimes, quality access control demands real-time hardware implementation to achieve low-power consumption, high-speed, and real time proce

A lifting based reversible data hiding is introduced here. The low–high subband is subdivided into little blocks of size (4 × 4), to generate a content dependent watermark. Then the access management is done by permutation of the content dependent

We present a theoretical investigation of coupling efficiency of a laser diode to a single-mode circular core triangular index fiber coupling via upside-down tapered hemispherical microlens on the tip of the fiber in presence of possible transverse a

In this paper, a hardware implementation of a data hiding technique is proposed for efficient quality access control of images using lifting-based discrete wavelet transformation (DWT). Host image is decomposed into n-level wavelet tiles. A binary wa
