Detection of Pathological Cells in Phase Contrast Cytological Images

Methods for Ellipse Detection from Edge Maps of Real Images

“…Specifically, it is important that the structures that are elliptical are indeed detected and the structures that are non-elliptical are not detected as (Antonaros and Petrou, 2001;Belaroussi et al, 2005;Bell et al, 2006;Burrill et al, 1996;Chia et al, 2009;Dijkers et al, 2005;Fernandes, 2009;Feyaerts et al, 2001;Foresti, 2002;Foresti et al, 2005;Fu and Huang, 1995;He et al, 2009;Hua et al, 2007;Hwang et al, 2006;Iles et al, 2007;Ji et al, 1999;Kayikcioglu et al, 2000;Kumar et al, 2009;Kuno et al, 1991;Liu et al, 2007;Lu et al, 2005;Matson et al, 1970;O'Leary et al, 2005;Prasad 2011c;Rosin and West, 1992;Salas et al, 2006;Shen et al, 2009;Shih et al, 2008;Smereka and Glab, 2006;Soetedjo and Yamada, 2005;Sood et al, 2005;Takimoto et al, 2004;Tang et al, 2000;Wang et al, 2006;Wu and Wang, 1993;Yuasa et al, 2004;Zaim et al, 2006;Zhang et al, 2003;Zhou and Shen, 2003;Zhou et al, 2009) ellipses. However, the problem of detecting ellipses in real images is very challenging due to many reasons.…”
