In a distributed environment, large data files remain a major bottleneck. Compression is an important component of the solutions available for creating file sizes of manageable and transmittable dimensions. When high-speed media or channels are used, high-speed data compression is desired. Software implementations are often not fast enough. In this paper, we present the very high speed hardware...

In this paper, a new lossless compression algorithm method for two-dimensional continuous-tone images is presented. The proposed method achieves higher compression ratios than universal methods. Traditional methods use coding techniques based on reduction of the existing redundancy in the data or pixels, mainly applying methods based on statistical models, substitution models, dictionary models...

A binary wavelet transform (BWT) has several distinct advantages over a real wavelet transform when applied to binary data. No quantisation distortion is introduced and the transform is completely invertible. Since all the operations involved are modulo-2 arithmetic, it is extremely fast. The outstanding qualities of the BWT make it suitable for binary image-processing applications. The BWT, or...

High performance Internet routers require an efficient IP lookup algorithm to forward millions of packets per second. Various binary trie data structures are normally used in software-based routers. Binary trie based lookup algorithms are simple not only for searching for the longest prefix match but also for updating the routing table. In this paper, we propose a new IP lookup algorithm based ...

Due to the prevalence of the Internet and multimedia, one can transmit a huge amount of data via the Internet. Image hiding techniques is often used to prevent data transmitted on a computer network from being hacked by unauthorized users. Generally, in a binary image, only the proximity of edge can be used to carry secret data. Since a little space in a binary image can be used to carry secret...

In reversible data hiding (RDH), the original cover can be losslessly restored after the embedded information is extracted. A famous author Kalker and Willems established a rate–distortion model for RDH, in which they proved out the rate–distortion bound and proposed a recursive code construction. In previous concept, improved the recursive construction to approach the rate – distortion bound B...

The Binary Pulse Compression system installed at SLAC was tested using two klystrons, one with 10 MW and the other with 34 MW output. By compressing 56@ ns klystron pulses into 70 ns, the measured BPC output wss 175 MW, limited by the available power from the two klystrons. This output was used to provide 10GMW input to a 36cell X-band structure in which a lOO-MV/m gradient was obtained. This s...
