Project: MERIT Toolbox Responsible Persons: Ivana Vujovic and Darko Jovic The goal of the project is to create a collection of procedures to be used by Fraunhofer IPSI group's watermarking software. These procedures are sometimes time-critical and therefore need to be implemented in Assembler code. The projects starting time is September 1st 2003 (In the following referred to as "T0"). Total project time span is 4 months. Part 1: Fast Fourier transformation (FFT) and inverse FFT (IFFT) The task for first part of the project is a fast Fourier transformation (FFT) and inverse FFT (IFFT). Part 2: The DCT Transformation The performance of MPEG Decoding is an important process for video watermarking. Some of the tasks inside the decoding process have a high complexity and are also time critical. One of them is the DCT Transformation so it needs to be transformed from C/C++ into Assembler. Part 3: Cryptographic methods for watermarking For watermark methods cryptographic methods are also important. This part of the project includes implementing RSA encryption in Assembler.
