A randomized covering-packing duality between source and channel coding will be discussed by considering the source coding problem of coding a source with a certain distortion level and by considering a channel which communicates the source within a certain distortion level. An operational view of ...

between the original signature and the extracted signature be as low as possible. In this work, we show that the above dual problems of data hiding and watermarking, readily map to the source and channel coding problem in digital communications. As such, established ...
Channel coding schemes can be generally divided into two classes,block codes and convolutional codes. In block coding, binary source output sequences of length k are mapped into binary channel input sequences of length n; therefore, the rate of the ...
The channel coding theorem states that for a DMS with entropy H(X) bits per symbol and emitting at 1/Ts symbols per second (called source average information rate) and a DMC with channel capacity C/Ts bits per symbol (called the critical rate), there exists a coding scheme for which the...
as the image size goes to inf inity, it is optimal to separately:1) compress the images as much as possible to remove redundant information (source coding) and2) use an error-correcting code to re-introduce redundancy, which allows for reconstruction in thepresence of noise (channel coding)...
Shannon's source-channel separation theorem, which proves the optimality of separating source and channel coding for point-to-point communication systems, hinges on the assumptions of unlimited complexity and delay in the system as well as an ergodic channel. While achieving optimal system performance...
