The new Motion JPEG 2000 standard is providing with some compelling features. It is based on an intra-frame wavelet coding, which makes it very well suited for wireless applications. Indeed, the state-of-the-art wavelet coding scheme achieves very high coding efficiency. In addition, Motion JPEG 2000 is very resilient to transmission errors as frames are coded independently (intra coding). Furt...

Since the standardization of the JPEG 2000, it has found its way into many different applications such as DICOM (digital imaging and communication in medicine), satellite photography, military surveillance, digital cinema initiative, professional video cameras, and so on. The unified framework of the JPEG 2000 architecture makes practical high quality real-time compression possible even in vide...

In this paper we present the behavior of JPEG2000 coding scheme over noisy or congested communication channels and highlight the cost analysis aspect. Two error schemes are considered including bit errors and packet dropping effects. Two bit error methods are used, consisting of flipping or dropping the bits, and various packet sizes are put to the test of packet dropping. Extensive performance...

JPEG2000 is the latest ISO/IEC image compression standard. It is distinct from previous standards in that it is more than an input-output filter. JPEG2000 enables decompression of many image products from a single compressed file and offers several opportunities for compressed domain processing. This paper describes the feature set of the JPEG2000 compression standard, followed by a high level ...

Financial institutions around theworld expected themillennium date change (Y2K) to cause an aggregate liquidity shortage. Responding to the concern, the Federal Reserve Bank of New York auctioned Y2K options to primary dealers. The options gave the dealers the right to borrow from the Fed at a predetermined interest rate. Using the implied volatilities of Y2K options and the on/off-the-run spre...

This contribution motivates and proposes the new idea of embedding and hiding a highlighting of particular regions within a raster image. Existing approaches tightly combine content and means for highlighting, and thus, do not allow access control to the emphasized contents or a removal of the accentuation. This is overcome by the introduced approach taking advantage of the Depth of Field effec...

Abstract : This paper presents a lossless image coding approach that produces an embedded bit−stream optimized for L−infinity−constrained decoding. The decoder is implementable using only integer arithmetic and is able to deduce from the bit−stream the L−infinity error that affects the reconstructed image at an arbitrary point of decoding. The lossless coding performance is compared with JPEG−L...

Projects can cause organizations to perform in new ways resulting in the generation of knowledge. Project learning occurs when new knowledge is captured, disseminated, and used by the project team. Y2K utility projects were studied with respect to knowledge benefits and management. Projects from developed countries using western technology were found to have knowledge benefits but their organiz...

There are many commercial tools that address various aspects of the Year 2000 problem. None of these tools, however, make any documented use of plan-based techniques for automated concept recovery. This implies a general perception that plan-based techniques is not useful for this problem. This paper argues that this perception is incorrect and these techniques are in fact mature enough to make...

Abstract: With the increasing use of multimedia technologies, image compression requires higher performance as well as new features. To address this need in the specific area of still image encoding, a ne...
