Abstract :
Based on the idea of the Blahut-Arimoto algorithm for computing channel capacities and rate-distortion functions, two iterative algorithms are developed for numerical computation of the compression and watermarking rate regions of joint compression and private watermarking systems with finite alphabets. The convergence of the algorithms developed is also proved
