In recent years, the use of video content has experienced exponential growth. The rapid growth led to an increased reliance on various codecs for efficient compression and transmission. However, several challenges are associated with such as H.265/High Efficiency Video Coding H.266/Versatile (VVC) that can impact quality performance. One significant challenge is trade-off between efficiency visual quality. While advanced significantly reduce file sizes, they introduce artifacts blocking,...

In recent years, video content has become a significant contributor to Internet traffic, prompting the development of efficient codecs, such as High Efficiency Video Coding (HEVC) and Versatile (VVC), reduce bandwidth usage storage requirements. However, these coding standards still exhibit quality degradation artifacts in decoded frames. To address this issue, researchers have introduced several network architectures based on deep-learning algorithms; however, most them focus in-loop...

The alteration, repackaging, and redistribution of multimedia content like image, video, audio, etc. poses a serious threat to both national security commercial markets. Presently with the growing popularity digital media world is becoming smaller smaller. That mainly due internet connectivity WWW phenomena. But copyright protection intellectual properties has become necessity for prevention illegal copying verification integrity. Here wavelet transform plays role an efficient robust tool...

The paper proposes an image watermarking scheme using wavelet domain. Wavelet transform, due to its sub bands decomposition, offers better trade-off between embedding strength and robustness performance compared other unitary transforms such as DCT, DFT, Fourier-Mellin, Walsh-Hadamard etc. Data in different of the cover resiliency against various types impairments. Degree is increased further by same watermark information multi-level coefficients image. Experiment results show that resilient...

The proliferation of the digitized media introduces an exigent problem security in multimedia data transmission network surroundings. Consequently, digital watermark technique needs to be incorporated a rights management framework address different aspects content management. objective is develop low power, real time, reliable and secure hiding system that can achieved all way through hardware implementation. As attempt towards power efficient system, here we present oblivious, spatial...

Spread Spectrum modulation has become a preferred paradigm in many watermarking applications. This paper analyzes the performance of such blind scheme under discrete wavelet frame rather than traditional orthonormal expansion. The over complete representation offered by redundant facilitates identification significant image features via simple correlation operation across scales. and resiliency proposed technique are analyzed against several volumetric distortion sources. experimental...

Advanced video codecs such as High Efficiency Video Coding/H.265 (HEVC) and Versatile Coding/H.266 (VVC) are vital for streaming high-quality online content, they compress transmit data efficiently. However, these can occasionally degrade quality by adding undesirable artifacts blockiness, blurriness, ringing, which detract from the viewer’s experience. To ensure a seamless engaging experience, it is essential to remove artifacts, improves viewer comfort engagement. In this paper, we propose...

This paper proposes an oblivious watermarking algorithm with blind detection approach for high volume data hiding in image signals. We present a reliable signal adaptive embedding scheme multiple messages selective sub-bands of wavelet (DWT) coefficients using direct sequence spread spectrum (DS-SS) modulation technique. Here the impact volumetric distortion sources is analyzed on ability analytical bounds order to recover watermark messages. In this context, joint source-channel coding has...
