講演タイトル:Constant-Working-Space Algorithms for Image Processing
      (講演はもちろん日本語です。)
アブストラクト:In this talk we present a new direction of algorithms for image processing. That is, we present algorithms which require no array of size depending on input image but use only constant working space, while keeping the running time. Three problems are considered. (1) Connected component labelling in which we label each pixel with its component number, (2) image-rotation with interpolation, and (3) image scan in an arbitrary slope. An input image of size O(n2) is stored in a two-dimensional array, but no other array is available for the algorithms. Our algorithms run in O(n2) time.
