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. The most distinctive difference between SVC and JPEG2000 is, in terms of spatialfrequency transformation, that SVC is based on the Discrete Cosine Transform (DCT) and JPEG2000 is based on Discrete Wavelet Transform (DWT). JPEG200...

this paper presents a new coding method for image compression based on jpeg2000 and contourlet transform. jpeg2000 standard is a common standard that uses discrete wavelet transform (dwt) in the compression process. the main problems of dwt are failure to detect curved edges in image and its shortage representation of the ridge and furrow patterns which cause deficiency and block artifacts rema...

This paper presents an efficient algorithm for post compression optimal rate allocation and packetization within JPEG2000 encoding. JPEG2000, the new ISO/ITU-T standard for still image coding, has been shown to provide superior coding efficiency to the previous standard, JPEG. However, the added efficiency of JPEG2000 comes at the cost of increased computational requirements. To improve the com...

The present paper will present a survey on features of a number of non-specialized off-the-shelf JPEG2000 viewers, seen from the point of view of digital microscopy. Selected viewers were tested within a number of usage scenarios, including: i) open a conformance test JPEG2000 file; ii) open a large JPEG2000 file; iii) moving from one point to another; iv) changing resolution/magnification. For...

In this work, JPEG2000 error resilience options and error concealment strategies are discussed and evaluated. Error resilience options and error concealment strategies have been employed to mimic attacks against selective / partial JPEG2000 encryption schemes. Thus the security evaluation of these selective / partial encryption schemes relies on the proper working of the JPEG2000 error concealm...

Information hiding in JPEG2000 compressed images is investigated in this research. The challenges of covert communication in this state-of-the-art image codec are analyzed and a steganographic scheme is then proposed to reliably embed high-volume data into the JPEG2000 bitstream. A special mode of JPEG2000 is employed, and its usage and functions are explained and justified. Experimental result...

JPEG2000 is the latest international standard for compression of still images. Although the JPEG2000 codec is designed to compress images, we illustrate that it can also be used to compress other signals. As an example, we illustrate how the JPEG2000 codec can be used to compress electrocardiogram (ECG) data. Experiments using the MITBIH arrhythmia database illustrate that the proposed approach...

In recent years, a number of backdoor attacks against deep neural networks (DNN) have been proposed. this paper, we reveal that are vulnerable to image compressions, as instances used trigger usually compressed by compression methods during data transmission. When compressed, the feature will be destroyed, which could result in significant performance degradation for attacks. As countermeasure,...

A great deal of computation for JPEG2000 encoding is a redundancy when the compression rate is high. That is because many coded bit-streams will be truncated after the rate control of JPEG2000. In this paper, an effective scheme for JPEG2000 rate control is proposed. Through this scheme, the computation complexity for JPEG2000 entropy coding, that is, EBCOT Tier-I, can be greatly reduced almost...

JPEG2000 is the latest still-image coding standard. It was designed to overcome the limitations of the original JPEG standard and provide high quality images at low bit rates. The JPEG2000 algorithm is fundamentally based on the Discrete Wavelet Transform (DWT) and Embedded Block Coding with Optimal Truncation (EBCOT). Both of the algorithms are computationally intensive and require significant...
