Since the introduction of JPEG 2000, several rate control methods have been proposed. Among them, post-compression rate-distortion optimization (PCRD-Opt) is the most widely used, and the one recommended by the standard. The approach followed by this method is to first compress the entire image split in code blocks, and subsequently, optimally truncate the set of generated bit streams according to the maximum target bit rate constraint. The literature proposes various strategies on how to… 


Efficient rate control for JPEG-2000
An integrated rate-control and entropy-coding (IREC) algorithm is proposed that reduces the computation complexity of entropy coding by selectively entropy coding only the image data that is likely to be included in the final bitstream, as opposed to entropy coding all image data.
Sample-parallel execution of EBCOT in fast mode
This paper evaluates how encoders targeting a parallel architecture such as a GPU can increase their throughput in use cases where very high data rates are used and chooses the fast mode after the fourth significant bit-plane to enable the Selective Arithmetic Coding Bypass style (fast mode).
Efficient rate control for JPEG2000 coder and decoder
An efficient rate control algorithm is described based on the interleaving of coding passes and it has a low computational complexity, which allows the extraction of a target bitrate from a codestream without the need of either knowing the original image, or of decoding any part of thecodestream.
A novel parallel Tier-1 coder for JPEG2000 using GPUs
The computation steps in JPEG2000 are examined, particularly in the Tier-1, and novel, GPGPU compatible, parallel processing methods for the sample-level coding of the images are developed.
Efficient rate control approach for JPEG2000 image coding
This work proposes an efficient rate control approach for the JPEG2000 encoder that reduces memory requirements and encoding time when compared with the existing rate control approaches for JPEG2000 standard, and also provides the same image quality as that of the PCRD approach used in the JPEG 2000 standard.
Effective hardware-oriented technique for the rate control of JPEG2000 encoding
By the proposed rate control method, a dedicated hardware of JPEG2000 with high-speed processing and effective rate control ability can be achieved.

A fine-granular parallel EBCOT is proposed by re-designing the highly serialized bit-plane coding to a parallel structure where the coding of all bits in a bit-planes could be performed in parallel, then the bit coding tasks can be distributed to the stream processors in GPU by taking advantage of the programming and memory model of CUDA.
GPU-Based Sample-Parallel Context Modeling for EBCOT in JPEG2000
This paper proposes a new parallel approach to EBCOT context modeling that truly exploits massively parallel capabilities of modern GPUs and enables concurrent processing of individual image samples.
Rate-distortion estimation for fast JPEG2000 compression at low bit-rates
A rate-distortion estimation method that enables precompression rate- Distortion optimisation to be carried out, wherein only the required passes need to be coded is presented.
Low Complexity JPEG2000 Rate Control Through Reverse Subband Scanning Order and Coding Passes Concatenation
A new rate control method devised to provide quality scalability to JPEG2000 codestreams containing a single or few quality layers based on a Reverse subband scanning Order and a coding passes Concatenation that does not use distortion measures based on the original image.
