  • field programmable gate array (FPGA);
  • image processing;
  • point operations


This chapter focuses on how specific image processing operations may be implemented on an field programmable gate array (FPGA). The simplest class of image processing operations is that of point operations. In spite of their simplicity, point operations have wide use in terms of contrast enhancement, segmentation, colour filtering, change detection, masking and many other applications. Thresholding is another common point operation, used for segmenting an image on the basis of intensity or colour. Point operations may also be applied between multiple images. Virtually any operation may be applied between the pixels of the images being combined. A common architecture is recursive processing, where a newly acquired image is combined with one or more images held in a frame buffer, with the result written back to the frame buffer.
