Varifocal-Net: A Chromosome Classification Approach Using Deep Convolutional Networks

Abstract: Chromosome classification is critical for karyotyping in abnormality diagnosis. To expedite the diagnosis, we present a novel method named Varifocal-Net for simultaneous classification of chromosomes type and polarity using deep convolutional networks. The approach consists of one global-scale network (G-Net) and one localscale network (L-Net). It follows three stages. The first stage is to learn both global and local features. We extract global features and detect finer local regions via the G-Net. By proposi… Show more

“…Researchers proposed and used various machine learning and deep learning techniques for automating the karyotyping process and obtained encouraging results. Most studies used deeply stacked convolutional neural networks for chromosome classification (Hu et al, 2019;Zhang et al, 2018;Sharma et al, 2018b and some studies employed feature based deep learning methods (Qin et al, 2019;Jindal et al, 2017).…”

“…However, despite that there are some methods have been developed to solve classification [7,10] and segmentation [2,6] problems of chromosomes, very few of the researches have tried to develop automated chromosomes enumeration method. Gajendran et.al [4] presented a study by combining a variety of preprocessing methods and counting algorithm based on topological analysis, but the error rate is high.…”
