Pictogram extraction algorithm for local and parallel processing

In this paper, we propose a new pictogram extraction algorithm which consists of only local processings. The proposed algorithm preserves accuracy with simple and local processing instead of high cost and global processings. This approach is very important for parallel image processing by a low cost device, because each pixel can be processed in parallel. The proposed algorithm can estimate degree of square by pixel count method to extract pictograms. The proposed algorithm has been tested using 100 scenery images. The effectiveness has been confirmed from the results of the computer simulations.
