Synchronization of Boolean networks with chaos‐driving and its application in image cryptosystem
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.

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
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.

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.

Curvelet Transform Based Compression Algorithm for Low Resource Hyperspectral Image Sensors
The wavelet transform is widely used in the task of hyperspectral image compression (HSIC). They have achieved outstanding performance in the compression of a hyperspectral (HS) image, which has attracted great interest. However, transform based hyperspectral image compression algorithm (HSICA) has low‐coding gain than the other state of art HSIC ...

A Multiresolutionnal Coding Method Based on SPIHT [PDF]
In this work, we incorporate a multiresolutional coding functionality into the SPIHT algorithm [1]. The multiresolutional coding can be considered as a kind of the region of interest (ROI) coding with multiple regions of interest. Therefore, the ROI coding proposed by authors can be extended for the multiresolutional functionality without any cost in ...

A blind contour‐aware quality model for sonar images
Abstract Since the penetration depth of visible light is limited in muddy and dark deep marine environment, sonar imaging, which is independent of natural light, has been attracting much attention in underwater detections. However, the visual quality of sonar image is inevitably damaged during the acquisition and the transmission in the sophisticated ...

Robust image transmission performed by SPIHT and turbo-codes [PDF]
This work describes the method for providing robustness to errors from a binary symmetric channel for the SPIHT image compression. The source rate and channel rate are jointly optimized by a stream of fixed-size channel packets. Punctured turbo codes are
