Abstract
This research contains an introduction to the first works in this field, and describes the Discrete Wavelet Transform DWT which is the only kind that can be implemented in the digital computer. The research lists the important structures that are used to implement the digital filters which are the hart of DWT. The research contains problems that face us in my M.Sc thesis to implement DWT image structure processor. In my M.Sc thesis we solve the problem of zero padding but we solve the second problem (waiting the column processor until the row processor finish its process) by using pipelineing technique. The pipeline technique solves the problem partially. This research solve the second problem completely by proposing a new structure which make the Two Dimentional DWT (2D-DWT) structure process the video in real time without waiting the row processor. The research was build fast structure that can decompose image by using DWT. The speed performance of the structure was tested using (Simulink) in (Matlab7). The results obtained from simulation of the proposed 2D DWT structure are compared with my M.Sc thesis structure and the traditional structure to show how we improve the process speed of 2D DWT structure.
