VLSI implementation of reconfigurable processing modulefor binary and grayscale image processing

In the field of image processing, binary images and grayscale images play a vital role in the application of object recognition, tracking, document analysis and authentication and machine intelligence. This paper proposes a reconfigurable processing module for image processor, in which the image processing functions and algorithms can be implemented, instead of using separate application specific integrated circuits (ASICs) for each algorithm. The reconfigurable module includes functions like basic mathematical morphological operations for binary and grayscale images and certain image processing algorithms. The reconfiguration module is implemented in field programmable gate arrays and compared with existing systems. The experimental and simulation results show that the module which has been implemented in the VIRTEX 4 XC4VLx15 device family at a 180-MHZ system clock and is suitable for real time image processing applications.
