The new image compression standard, JPEG2000, provides higher compression rates for the same visual quality for grayscale and color images than JPEG. JPEG2000 is being adopted for image compression and transmission, e.g. in mobile phones, PDAs, and wearable computers. Depending on the application, images may contain formatted text and graphics data. For graphics images at the same low bit rates...

The scalable extension to the H.264/AVC has been established as a Scalable Video Coding (SVC) standard, and JPEG2000 is a state of the act still image coding standard. SVC is based on the Discrete Cosine Transform (DCT) and JPEG2000 is based on Discrete Wavelet Transform (DWT). Despite the DWT has been successfully employed in still image coding, the latest video coding standard keeps on ultili...

The efficient compression of medical images is important for improved storage and network utilization. The Joint Photographic Experts Group (JPEG) baseline compression algorithm has been widely used in medical image compression. In contrast, JPEG2000 is a relative new compression standard. The purpose of this study is to provide a quantitative comparison of JPEG and JPEG2000 compression effects...

Sydney, Australia, provides a broad and solid foundation for applications using JPEG2000*. The Kakadu Software Development Kit (SDK)* is a comprehensive, heavily optimized, fully compliant software toolkit offered to JPEG2000 developers through Kakadu customers, who are independent software vendors (ISVs). Through this software framework, which provides a solid foundation for a range of both co...

JPEG2000 is a wavelet transform based image compression and coding standard. It provides superior rate-distortion performance when compared to the previous JPEG standard. In addition JPEG2000 provides four dimensions of scalability—distortion, resolution, spatial, and color. These superior features make JPEG2000 ideal for use in power and bandwidth limited mobile applications like urban search ...

The advent of new technologies such as high dynamic range or 8K screens has enhanced the quality digital images but it also increased codecs’ computational demands to process data. This paper presents a video codec that, while providing same coding features and performance those JPEG2000, can 16K in real time using consumer-grade GPU. throughput is achieved with technique that introduces comple...

ABSTRACT To overcome many drawbacks in the current JPEG standard for still image compression, a new standard, JPEG2000, is under development by the International Standard Organization. Embedded bit plane coding is the heart of the JPEG2000 encoder. This encoder is more complex and has significantly higher computational requirements compared to the entropy encoding in current JPEG standard. Beca...

In this work, a scalable perceptual JPEG2000 encoder that exploits properties of the human visual system (HVS) is presented. The algorithm modifies the final three stages of a conventional JPEG2000 encoder. In the first stage, the quantization step size for each subband is chosen to be the inverse of the contrast sensitivity function (CSF). In bit-plane coding, two masking effects are considere...

In this paper, a novel selective encryption scheme for JPEG2000 codestream is proposed. Many of proposals format compliant encryption schemes for JPEG2000 that have been made encrypt packet body data, but leave header packet in plaintext. Our proposed scheme encrypts code-blocks data corresponding to some sensitive precincts. This encryption is combined to a cyclic permutation of all packets he...

This paper presents an error concealment technique for image transmission in JPEG2000 for the lowest frequency coefficients. The proposed method uses the layer structure that is a feature of the JPEG2000. The most significant layer is hidden in place of the lowest layer of the bit stream. After transmission this embedded layer is used for error concealment. The bit stream encoded using the prop...
