“…The Zheng & Zheng (2010) proposal builds upon earlier studies of logic systems from a structural viewpoint. Kunii & Takai (1989) applied a n-cell structure for analysis, classification and generation of visual objects using topology and homotopy tools in computer graphics (Kunii, Hioki & Shinagawa, 1993;Kunii & Kunii, 1999;Kunii & Shinagawa, 1992;Kunii & Takahashi, 1993;Kunii, Tsuchida, Arai, Matsuda, Shirahama & Miura, 1993). Zheng & Maeder (1992) proposed a balanced classification on binary images for conjugate classification and transformation of binary images on regular plan lattices in 1990s to visualise different configurations (Zheng, 1994;1996;Zheng & Leung, 1996;Zheng & Maeder, 1993).…”
