Synchronization of Boolean networks with chaos‐driving and its application in image cryptosystem
IET Image Processing, Volume 17, Issue 14, Page 4176-4189, 11 December 2023., 2023 This paper proposes a Boolean network model with high dimensional chaos driving and studies the synchronization of the chaos driving Boolean network with a semi‐tensor product. In addition, the synchronization results are utilized in the image cryptosystem to achieve compression and encryption.

IET Image Processing, Volume 17, Issue 10, Page 2984-3001, 21 August 2023., 2023 In IoT sensors, which are used to record and send images, secure image transmission is of great importance. Therefore, we need to use encryption, watermarking and compression processes. Here, a new integrated method of lightweight encryption, watermarking and compression for the fast and secure transmission of images is proposed.

LL‐FMC: Low‐latency frame memory compression scheme with high reconstructed quality
Electronics Letters, Volume 59, Issue 14, July 2023., 2023 This study proposes a Huffman coding with a fixed codebook designed to considerably reduce the latency caused by arithmetic coding in lossless compression schemes. This study also proposes a novel lossy frame memory compression technique based on the Hadamard transform that does not require additional memory access using a lookup table.

The Journal of Engineering, Volume 2023, Issue 6, June 2023., 2023 Abstract Transmitting images over an Orthogonal Frequency Division Multiplexing Access (OFDMA) system poses a significant challenge. The process entails sending a substantial amount of data, which consumes a significant amount of bandwidth. Consequently, compressing the transmitted image becomes essential to reduce the required bandwidth.
