Breast Cancer Histological Images Nuclei Segmentation using Mask Regional Convolutional Neural Network

Abstract

the breast cancer cases have increased globally, in the last two decades. Analysis of histological images acquired through biopsy of the breast tissues is thought to be the most reliable way to assess if any cells show signs of malignancy. With the advent of deep neural networks, we are now able to diagnose the disease with near perfect accuracy instead of conventional techniques of mammography for breast cancer detection; however, work done in this area considers nuclei segmentation. This work is focussed on extending the applicability of deep learning technology where network is trained to perform segmentation and classify data as one of the four classes: normal, benign, in-situ and invasive. The classification accuracy achieved is 98.16% and the segmentation accuracy calculated using overlap coefficient from mean intersection over union is 86.39% on the ICIAR2018 Breast Cancer dataset.
