An Integrated curvature and Convex Hull based concave point detection in Histopathological images

Abstract

We propose a simple approach to identify concave points in Histopathological Images. Identification of all valid concave points play an important role in separating irregular shaped cells forming clumps in the Histopathological images. There exists several studies for accurate identification of concave points. Our experimental analysis reveal that existing methods fail to identify both deep, and shallow concave points. In this paper we propose an integrated curvature and convex hull based concave points detection in Histopathological images. The proposed method performed well when compared to the existing methods.
