In this paper, we analyze the performance of Motion JPEG2000 for wireless applications. This new standard is based on intra-frame wavelet coding. Motion JPEG2000 is offering a number of very compelling advantages when compared to state-of-the-art MPEG-4 video coding. Wavelet coding achieves very high coding efficiency. Furthermore, because frames are intra coded, it is very error-resilient. Fin...

This paper proposes a post-processing technique for reducing tile boundary artifacts which occur in an image when it is compressed at low bit rate using JPEG2000 standard. Symmetric extension and difference in quantization accuracy between the tiles of the image are the main factors behind the tile boundary artifacts in JPEG2000 compressed images. In this paper, we have analyzed the effect of q...

The JPEG2000 standard was developed to address a wide range of video and imaging applications, including medical imaging, military and security systems, and digital cinema. To enable these applications, JPEG2000 has many unique features, including scalability, support for regions of interest, lossless support, and low latency. Digital signal processor-based JPEG2000 solutions are available, but...

JPEG2000 is the new standard for the compression of images, which succeeds to JPEG. It’s has a much higher algorithmic complexity. The complexity of the entropy encoder ( EBCOT) is the most significant in JPEG2000. Which alone constitutes about 70% of the overall processing time for compression of an image. This new standard has many features and characteristics (region of interest, several typ...

The JPEG2000 syntax requires that any two consecutive bytes in the encrypted packet body should not be larger than 0xFF8F. This stringent requirement has plagued researchers for a few years. In this paper, we present a novel secure encryption and authentication scheme for JPEG2000 code-streams, which does not introduce superfluous JPEG2000 markers in the protected code-stream. The scheme achiev...

Equal bit rate is assigned to all tiles of an image when compressed with JPEG2000 standard. This bit rate is selected without taking information contents of the tiles into account. This results into poor performance of JPEG2000 standard for the tiles that have higher complexity. We can improve performance of JPEG2000 by assigning higher bit rates to complex tiles. An entropy based weighted bit ...

The goal of this research is to examine the feasibility of implementing face recognition algorithms directly into JPEG2000 compressed domain. By exploring some standard face recognition algorithms' behavior when fed with standard JPEG2000 DWT coefficients (CDF 9/7 wavelet), we will prove that recognition can be done directly in JPEG2000 compressed domain, avoiding inverse discrete wavelet trans...

It is well known that tile boundary artefacts occur in lossy wavelet-based image coding [1, 2, 3, 4, 5]. The base model of the JPEG2000 standard (ie JPEG2000 Part I) suffers from these artefacts, being a wavelet-based coding system. This paper analyses the tile boundary problems of JPEG2000 Part I and presents a novel method for reducing these tile boundary artefacts. This method has recently b...

The new image compression standard JPEG2000, provides high compression rates for the same visual quality for gray and color images than JPEG. JPEG2000 is being adopted for image compression and transmission in mobile phones, PDA and computers. An image may contain the formatted text and graphics data. The compression performance of the JPEG2000 behaves poorly when compressing an image with low ...
