Perceptual Quality Assesment for Video Watermarking

چکیده
The reliable evaluation of the performance of watermarking algorithms is difficult. An important aspect in this process is the assessment of the visibility of the watermark. In this paper, we address this issue and propose a methodology for evaluating the visual quality of watermarked video. Using a software tool that measures different types of perceptual video artifacts, we determine the most relevant impairments and design the corresponding objective metrics. We demonstrate their performance through subjective experiments on several different watermarking algorithms and video sequences.

متن کاملTwo Novel Chaos-Based Algorithms for Image and Video Watermarking
In this paper we introduce two innovative image and video watermarking algorithms. The paper’s main emphasis is on the use of chaotic maps to boost the algorithms’ security and resistance against attacks. By encrypting the watermark information in a one dimensional chaotic map, we make the extraction of watermark for potential attackers very hard. In another approach, we select embedding po...
متن کاملRobust multiplicative video watermarking using statistical modeling
The present paper is intended to present a robust multiplicative video watermarking scheme. In this regard, the video signal is segmented into 3-D blocks like cubes, and then, the 3-D wavelet transform is applied to each block. The low frequency components of the wavelet coefficients are then used for data embedding to make the process robust against both malicious and unintentional attacks. Th...
متن کاملPractical, Real-Time, and Robust Watermarking on the Spatial Domain for High-Definition Video Contents
Commercial markets employ digital right management (DRM) systems to protect valuable high-definition (HD) quality videos. DRM system uses watermarking to provide copyright protection and ownership authentication of multimedia contents. We propose a real-time video watermarking scheme for HD video in the uncompressed domain. Especially, our approach is in aspect of practical perspectives to sati...
متن کاملA Subjective Method to Estimate the Voice Quality for Speech Watermarking Based on Improved Spread Spectrum Technique
This paper investigates the measure of voice quality for a digital speech watermarking scheme using a subjectivity method. Data rate, inaudibility, and robustness are considered more than voice quality in speech watermarking. Since any technique in speech telecommunication should have acceptable quality, the perceptual measurement of voice quality is seen as an important topic in audio and spee...
