We present a new class of iteratively decodable turbo-like codes, called braided convolutional codes. Constructions and encoding procedures for tightly and sparsely braided convolutional codes are introduced. Sparsely braided codes exhibit good convergence behavior with iterative decoding, and a statistical analysis using Markov permutors shows that the free distance of these codes grows linearly...
Traditional watermarking techniques based on fractal coding are generally using 0, 1 sequence as watermark, thus impossible for gray image embedding. A novel fast watermarking technique is proposed in this paper to overcome the above mentioned shortage by employing the orthogonal fractal coding technique. With the proof that fractal decoding parameters during iterations is mean-invariant, watermarks...
