HVS-based rate-control scheme for object-based embedded image coding by Dong-jie LI, Zhong-jie ZHU, Yu-er WANG

“…A new rate control algorithm for object-based embedded coding was proposed by incorporating the characteristics of human visual systems (HVS).Firstly,the importance and coding priority of each visual object were estimated.Then,bit-plane modeling and entropy coding were implemented for each object based on the coding priority and its corresponding bit stream was outputted.Finally,bit streams of visual objects were truncated and reassembled based on the rate-distortion optimization principle under the given bit rate.Experimental results reveal that the proposed algorithm can encode and transmit different important objects with different strategies.Compared with the PCRD algorithm,the proposed algorithm can improve the overall visual quality of the reconstructed image.…”

Block Markov superposition transmission over turbulence channels in outdoor optical wireless communication by Jin-shun ZHU, Xiao MA

“…Based on the equivalent genie-aided system,the bit-error rate of the block Markov superposition transmission system was analyzed and the union bound of the bit-error rate of the genie-aided system was derived.When the bit-error rate was extremely low at which the Monte Carlo simulation was time-consuming,the union bound could be adopted to evaluate the performance of the block Markov superposition transmission system.Simulations under turbulence conditions from weak to strong are performed which show that,in the low bit-error rate region,performance of the block Markov superposition transmission system matches well with the lower bound.It is also illustrated that the derived union bound matches well with Monte Carlo simulation result.At the BER of 10^-5,block Markov superposition transmission system with transmission memory 2 performs within 1 dB away from the Shannon limit.…”

Confidential communication scheme based on uncertainty of underwater noisy channels by Ming XU, Fang CHEN

“…Aiming at the influence of the uncertainty of underwater noise on information transmission and the security problem of the communication over noisy channels,a confidential communication scheme based on the uncertainty of underwater noisy channels was proposed.The proposed scheme was composed of an interactive key extraction protocol based on Godel’s code and a privacy amplification protocol based on r-circulant Toeplitz matrix.During the process of key extraction,the key sequence comparing number was reduced through the Godel’s code.When calculating the key length after privacy amplification,the uncertainty of underwater noise was considered to make the proposed scheme more practical.Experimental results show that under the condition of satisfying protocol security,it takes 11.99 s to transmit 119 940 bit string where the lower bound of the generated secret key length is 117 331 bit after privacy amplification and the upper bound of the adversary’s information about the secret key is 2 609 bit.Moreover,the proposed scheme (nt+s)×(nt+s)-order r-circulant Toeplitz matrix decreases(nt+s)-1 bit memory space compared to the traditional Toeplitz matrix with the same order.…”

Reversible data hiding in encrypted images based on additive homomorphic encryption and multi-MSB embedding by Wenqian XIAO, Gaobo YANG, Dewang WANG, Ming XIA

“…Reversible Data Hiding in Encrypted Images (RDHEI) combines image encryption and reversible data hiding to improve the security and information transmission efficiency for the network transmission of images.In RDHEI, the conventional bit-by-bit encryption destroys the spatial correlation in an original image and has side effects on the preservation of embedding spaces.An approach for RHDEI was proposed, which utilized additive homomorphic encryption and a multi-MSB (Most Significant Bit) embedding strategy to create room within the encryption process.The original image was divided into non-overlapped blocks, and each block was subjected to the same key for additive homomorphic encryption.This helped transfer the pixel correlation within an original block to the encrypted image block as much as possible.To enhance security, the encrypted image was further subjected to an Arnold transformation on a block-by-block basis.The decision of whether data will be embedded in a block and the embedding capacity were determined by the pixel differences within the block and the predicted values.When a block was selected for embedding, a small number of LSBs (Least Significant Bits) were used to store the prediction differences, ensuring reversibility.The redundant multi-MSBs were embedded with secret information by bit replacement.For the possible errors caused by multi-MSBs prediction, an embedding position selection strategy was designed by vacating MSBs in terms of the values of prediction errors, then more MSBs were reserved for those pixels with less prediction errors.During decryption, the secret information can be accurately extracted from the multiple MSBs of the pixels in a block, and the image content can be losslessly recovered using the number of embedded multi-MSBs, predicted values, and prediction differences.Experimental results on the BOWS-2 image dataset demonstrate that the average embedding capacity is improved to 2.58 bit/pixel, surpassing existing methods.…”
