There is a lot of research going on to find a stenography technique which is not only imperceptible but also has other two features, namely, high embedding capacity and robustness. Imperceptibility is the most important requirement of steganography followed by high capacity. In this paper we give an overview of high capacity image steganographic techniques and propose a novel imperceptible and ...

Video steganography has become due to the significant growth of video data over performance of any steganography algorithm factors: embedding efficiency and embedding paper, a high embedding payload of vide algorithm has been proposed based on the improve the security of the algorithm, a secre encoded by , , coding. Then, it is em discrete wavelet transform (DWT) coefficients As the DWT middle ...

Steganography is the process of hiding a secret message within a larger one in such a way that someone cannot know the presence or contents of the hidden message. The purpose of Steganography is to protect the hidden information from the outside world and the security will increase if the secret information can’t be retrieved even if the attacker has the idea of embedding method. The proposed t...

Payload tracking maintains alignment between a payload and a target while both payload and target may be moving. This research investigates the generic problem of tracking from a mobile robot. A tracking strategy based on subsystem interactions is developed along with tools to model and evaluate payload tracking, metrics for evaluating tracking configurations , and guidelines for developing con...

This memo describes an RTP payload format for scalable video coding (SVC) defined in_Annex G of the ITU-T Recommendation H.264 video codec which is technically identical to Amendment 3 of ISO/IEC International Standard 14496-10. The RTP payload format allows for Wenger, Wang, Schierl Expires August 24, 2008 [Page 1] Internet-Draft RTP Payload Format for SVC Video February 2008 packetization of ...
