This paper presents a novel modification of integer arithmetic code, which performs compression and encryption at the same time. It is quite different from the randomized arithmetic code (RAC), the interval splitting arithmetic code (ISAC), and the secure arithmetic code (SAC). In security, we apply the Pseudo-Random Bit Generator (PRBG) and the Secure Hash Algorithm (SHA-256) to construct the key...
According to the correlation and statistical information of neighboring pixels in image, a statistical morphological predict operator is constructed based on the Markov random field theory, and the corresponding 2-D statistical morphological wavelet is also defined. Under the conditional probability density function in MRF model, It can be proved that more detail coefficients approach to zero after...
