1. 16. Independent Domain of Symmetric Encryption using Least SignificantBit : Computer Vision, Steganography and Cryptography Techniques

   Magister-uppsats, Högskolan Dalarna/Datateknik

   Författare :Bhupathi Rajan Guruswamy Aarumugam; [2011]
   Nyckelord :Image watermarking; LSB; Vigenere Square; AI Techniques; Computer Vision; Steganography and Cryptography;

   Sammanfattning : The rapid development of data transfer through internet made it easier to send the data accurate and faster to the destination. There are many transmission media to transfer the data to destination like e-mails; at the same time it is may be easier to modify and misuse the valuable information through hacking. LÄS MER

3. 17. Unequal Error Protection for Wireless Imaging

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Sandya Rondla; [2009]
   Nyckelord :UEP; JPEG; ROI; BCH codes; Hamming codes; Gaussian channel; and Rayleigh fading.;

   Sammanfattning : This thesis work was to examine the unequal error protection (UEP) scheme for joint photographic experts group (JPEG) 2000 images over an additive white Gaussian noise (AWGN) and a Rayleigh fading channel. The JPEG 2000 standard provides an effective image compression that result in increasing effect of transmission errors. LÄS MER

4. 18. Implementation and Comparison of Motion Estimation Algorithms for Video Coding

   Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

   Författare :Ferhat Erdogan; [2005]
   Nyckelord :video coding; motion estimation; motion compensation;

   Sammanfattning : In video coding, motion compensated prediction between the frames is a very efficient way for exploiting temporal correlation. Different motion estimation algorithms have been developed in order to provide efficient motion compensated prediction of scene motion between frames. LÄS MER
