An FPGA Accelerator for Real-Time Lossy Compression of Hyperspectral Images
TL;DR: JYPEC, a lossy hyperspectral compression algorithm that combines PCA and JPEG2000, is accelerated using an FPGA, showing a performance comparable to that of existing 0.18 μm CMOS implementations, all while keeping a small footprint on FPN resources.

An efficient hardware implementation of MQ decoder of the JPEG2000
TL;DR: A novel architecture for a MQ decoder with high throughput which is comparable to that of other architectures and suitable for chip implementation is proposed and implemented in VHDL hardware description language and synthesized using Xilinx and Altera design flows respectively.

A High-Throughput VLSI Architecture Design of Arithmetic Encoder in JPEG2000
TL;DR: A “index-arbiter” method is introduced in order to prevent the AE from stalling when the burst number of the context is larger than one, and the throughput has been increased by 37 %.

High performance scalable image compression with EBCOT
TL;DR: A new image compression algorithm is proposed, based on independent embedded block coding with optimized truncation of the embedded bit-streams (EBCOT), capable of modeling the spatially varying visual masking phenomenon.
An overview of the JPEG2000 still image compression standard
Majid Rabbani,Rajan L. Joshi +1 more
TL;DR: The JPEG2000 standard as discussed by the authors is an International Standard (ISO 154447ITU-T Recommendation T.800) that is being issued in six parts (Part 1, in the same vein as the JPEG baseline system, is aimed at minimal complexity and maximal interchange and was issued as an International standard at the end of 2000.

An overview of the JPEG 2000 still image compression standard
Majid Rabbani,Rajan L. Joshi +1 more
TL;DR: Although the JPEG 2000 standard only specifies the decoder and the codesteam syntax, the discussion will span both encoder and decoder issues to provide a better understanding of the standard in various applications.

An overview of the basic principles of the Q-Coder adaptive binary arithmetic coder
TL;DR: The Q-Coder as mentioned in this paper is a new form of adaptive binary arithmetic coding, which is derived from the basic concepts introduced by Rissanen, Pasco, and Langdon, but extends the coding conventions to resolve a conflict between optimal software and hardware implementations.

JPEG2000: the upcoming still image compression standard
TL;DR: A new standard is currently being developed, the JPEG2000, which is not only intended to provide rate-distortion and subjective image quality performance superior to existing standards, but also to provide functionality that current standards can either not address efficiently or not address at all.
