A novel architecture has been proposed based on the C-MOVE microprocessor for the fast and efficient parallel structural decomposition, W-H transform and encoding of digital images. A hierarchical and reconfigurable tree of interconnected processors is used to implement the W-H transform of an image which is already preprocessed and decomposed into a succession of consecutive “quadrant” sub-pictures. The regular decomposition procedure is followed to develop the quad-tree structure associated with a given image. Then a parallel algorithm is developed for the realization of the W-H transform of the given image. The W-H transform of the whole picture can be implemented by parallelprocessing. The C-MOVE architecture has been invoked for the realization of the above mentioned scheme. The C-MOVE architecture can prove to be extremely economical and fast, especially when a large number of parallel processors is utilized. The tree-structure of the decomposed picture and the proposed hierarchically distributed processing scheme match very well, resulting in a very flexible and adaptable architecture for implementing an image processing scheme. The proposed scheme uses C-MOVE processors to implement all the modules of the system. The architecture presented exhibits a high degree of parallelism with the main processing modules sharing the same main memory and exchanging data over the common very high speed bus, under the control of the master-controller processor. Each module works independently on the assigned task once the data and instruction string have been loaded in its part of memory. Meanwhile, the picture preprocessing module is freed to proceed on the next step of the regular decomposition algorithm.
