8-10 濃淡画像の零交差線検出アルゴリズムに関する一検討(修正版)(第8部門 メディア工学3)

抄録

Previously, the zero-cross detection algorithm has been proposed. In this article, we define the lines of slope which are drawn from maxima to minima and propose the zero-cross detection algorithm for gray image by determining the concavity and convexity along the slope.
