Digital Watermarking Techniques : The Studies
Few Digital Watermarking Techniques studies with intriguing findings could be found.
Watermarking technique: Wavelet-based watermarking
A study about watermarking techniques. There are a few different watermarking techniques that can be completed in order to protect copyrighted materials. One is to use a spatial domain watermarking technique, which is used when the mark is centered on a particular area in an image. Another is to use a transform domain watermarking technique, which is used when the mark is associated with a transformation that has been applied to an image. Finally, the strongest watermarking technique known today uses wavelet-based watermarking technology, which was first developed for security reasons. Each of these different watermarking techniques has its own strengths and weaknesses, which can be determined depending on the specific needs of the creatorship information being protected.
Watermarking Increases Image Noise and Resolution
A journal about the effect of watermark on digital images has been conducted which found that the presence of a DCT watermark influences the quality of digital images. The study was done on images taken from Google Earth and found that the presence of the DCT watermark increases image noise and reduces image resolution.
Watermarking techniques for images - different options for high-quality output
A research about digital watermarking techniques has been carried out to determine the best ones for various applications. Techniques were found that extract watermark from images without undesirable properties, making them ideal for various applications.
Digital Watermarking with Wavelet-Based Techniques
An evaluation about digital watermarking, applications and its various uses has been conducted. This paper describes the various digital watermarking techniques and how they can be used in different contexts. The study finds that Wavelet-based digital image watermarking is one of the most efficient and accurate methods for marking images. This technique can be used for an variety of purposes, such as censorship, legal judgement, and fingerprint recognition.
Data Watermarking and Authentication: A Means to Keep Images Authentic
An inquiry about digital watermarking has shown that it is a means for ensuring the authenticity of digital images. By leaving a digital watermark on an image, researchers can ensured that no one can tamper with the data or remove information from the image without notifying the photographer first.
The challenges of digital watermarking in multimedia information protection
A journal about digital watermarking techniques used in the field of multimedia information protection has been conducted. The study has found that present digital watermarking techniques are not efficient enough to protect multimedia information. They can be easily copied and distributed, which makes them a weak security system.
Digital watermarking technology: unique images without losing detail
A paper about the digital watermarking techniques is presented. dispersing a digital image into 11 frequencycomponent modules, each with its own transform, allows for watermarking algorithms to generate unique images. For example, the proposed singular value decomposition (SVD) algorithm is able to separably identify objects in an image while still preserving its detail. With this technology, it is possible to prevent unauthorized users from extracting information from a Blu-ray or DVD.
The Effect of Digital Watermarking Techniques on Media Quality
A study about digital watermarking techniques has been undertaken and found to be effective in enhancing the quality of digital media. Watermarking is the process of embedding watermarks in media e.g. audio, video, image etc. using an algorithm. This study found that a number of digital watermarking techniques are effective in achieving desired results while taking into account thepost-processing concerns inherent to each technique.
Watermarking Technology: A Comprehensive Guide
A research about digital watermarking methods has been conducted, and it has found that various techniques are useful for achieving this goal. For example, inverted watermarking can be used to disguise material from being seen by unauthorized individuals. Additionally, cryptographic watermarking is useful in secure communications to help protect the data from being compromised.
Digital Watermarking Techniques: Evaluating Their Effectiveness
A study about digital watermarking techniques was undertaken to determine whether or not it can provide adequate protection for copyrighted materials. Many different methods have been evaluated, with the goal of arriving at a final decision that is both effective and efficient. It was found that some digital watermarking techniques are more effective than others in order to achieve the desired goals.
