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.
