Performance requirements of the Mojette transform for internet distributed databases and image processing

In the last ten years there were intensive researches to find new methods for handling Internet distributed databases and image processing. One of these methods is the Mojette transform (MOT). This transform is an exact discrete Radon transform defined for a set of specific projections. The MOT is used mainly in image processing applications. There were several implementation using personal computers [8] and [9], but these application were implemented only for locally stored images. There are some applications where real time computing is a must, but the implementations before referred can not accomplish this requirement. The Mojette transforms implemented under different operating systems and for different processors presented below helps the performance analyses of the MOT and also let to conclude the need for reconfigurable hardware implementation. There is also analyzed the implementation of Mojette transform and inverse Mojette transform (IMOT) the implementation in field programmable gate arrays using reconfigurable platform. The paper tries to conclude the necessity for hardware implementation for real time processing. The paper outline the development work in order to create an embedded reconfigurable hardware based on FPGA board.
