A Robust Convergence Index Filter for Breast Cancer Cell Segmentation
COnvergenceINdex (COIN) filter, a successful tool for 
cell localization, evaluates the degree of convergence of 
the gradient vectors within the neighborhood (region of
support) toward a pixel of interest. The adaptability of the
region of support was increased to make COIN filter robust
and accurate. However, improving the quality of the image 
gradient map was ignored which results in poor performance 
of the members of the COIN family in noisy setting. We 
propose a new Robust Convergence Index (RCI) filter that
tailors COIN filter in noisy environment by (a) spreading 
the gradient vectors within non-homogeneous object 
regions through the convolution of an Aggregated Edge 
Probability Map (AEPM) based weighted edge map by an
edge preserving gradient vector kernel, and (b)increasing the 
convergence of the gradient vectors through the integration
of the sine and cosine distribution as well as the magnitude 
of the gradient vectors. AEPM is computed through the 
consensus of the responses of a number of edge detectors 
over a wide range of scales which lessen the effects of 
clutter by enforcing higher weights to the actual edges, and 
then a non-parametric KDE is used to compute the edge 
probability map.Experimental results demonstrate that it 
obtains state-of-the-art performance.
