The rapid spread of digital media (audio, images and video) and the ease of their reproduction and distribution has created a need for copyright enforcement schemes in or- der to protect content creators and owners. In recent years, digital watermarking has emerged as an effective way to prevent users from violating copyrights. This concept is based on the insertion of information into the data in such a way that the added information is not perceptible yet resis- tant to (intentional or unintentional) alterations of the wa- termarked data. Three factors must be considered in image or video wa- termarking:

  • Capacity, i.e. the amount of information that can be put into the watermark and recovered without errors;
  • Robustness, i.e. the resistance of the watermark to alterations of the original content such as compression, filtering or cropping;
  • Visibility, i.e. how easily the watermark can be discerned by the user.
These factors are inter-dependent; for example, increasing the capacity will decrease the robustness or increase the vis- ibility. Therefore, it is essential to consider all three factors for a fair evaluation or comparison of watermarking algorithms.

We have developed a fast scheme for Wavelet-based video watermarking that is capable to process frames quickly and efficiently.

Index Terms: Matlab, source, code, video, watermarking, wavelet, watermark.

New - AI Trader
 Stock Price Trend Forecasting An emerging trading market is represented by binary options. Binary options are a convenient way of investments as they donít require a trader to forecast actual quotes.
 
New - Speaker Verification System
 Text-Independent Speaker Authentication There are two major applications of speaker recognition technologies and methodologies. If the speaker claims to be of a certain identity and the voice is used to verify this claim, this is called verification or authentication.
 
New - Java Face Recognition
 Java-based Biometric Authentication System Face recognition is essential in many applications, including mugshot matching, surveillance, access control and personal identification, and forensic and law enforcement applications.

New - White Papers
 High Capacity Wavelet Watermarking Using CDMA Multilevel Codes This paper proposes a technique based on CDMA and multilevel coding in order to achieve a high capacity watermarking scheme. The bits of watermark are grouped together and for each sequence a different modulation coefficient is used.
 
New - WebCam Face Identification
 Face Recognition Based on Fractional Gaussian Derivatives Local photometric descriptors computed for interest regions have proven to be very successful in applications such as wide baseline matching, object recognition, texture recognition, image retrieval, robot localization, video data mining, building panoramas, and recognition of object categories.
 
New - Speaker Recognition System
 Source code for speaker recognition
Speaker recognition is the process of automatically recognizing who is speaking on the basis of individual information included in speech waves.
 
New - Speech Recognition System
 Source code for isolated words recognition
Speech recognition technology is used more and more for telephone applications like travel booking and information, financial account information, customer service call routing, and directory assistance. Using constrained grammar recognition, such applications can achieve remarkably high accuracy.
