High speed VLSI architectures for DWT in biometric image compression: A study

AbstractBiometrics is a field that navigates through a vast database and extracts only the qualifying data to accelerate the processes of biometric authentication/recognition. Image compression is a vital part of the process. Various Very Large Scale Integration (VLSI) architectures have emerged to satisfy the real time requirements of the online processing of the applications. This paper studies various techniques that help in realizing the fast operation of the transform stage of the image compression processes. Various parameters that may involve in optimizations for high speed like computing time, silicon area, memory size etc are considered in the survey

Substrate-controlled stereoselective synthesis of ophiocerin C

A novel stereoselective total synthesis of ophiocerin C was accomplished starting from L-(+)-tartaric acid. The C3,C4 vic-diol moiety was obtained from tartaric acid, and the stereogenic centre at C6 was created by substrate-controlled epoxidation and subsequent regioselective cleavage of the epoxide ring
