Benchmarking HEp-2 Cell Segmentation Methods in Indirect Immuno-Fluorescence (IIF) Images - Standard Models to Deep Learning


In this work, we provide a systematic review of different human epithelial (HEp-2) cell segmentation methods on indirect immunofluresence (IIF) images. Our review covers traditional image processing (thresholding, Otsu, watershed, active contours), machine learning (auto-learning, random forest), and deep learning (DL) methods for segmenting HEp-2 cells. We extensively benchmark various DL cell segmentation models such as convolutional neural networks (CNNs), generative adversarial networks (GANs) for segmenting HEp-2 cells from IIF images. Our results indicate that DL models achieve better segmentation accuracy than traditional image processing, machine learning models with ResNet50-U-Net being the top model overall.

HE-2 Cell Segmentation - Benchmarking CNN/GAN Models

For cell segmentation, we benchmarked the following DL models: U-Net, VGG, ResNet, SegNet, MobileNet along with GAN-based approaches. Our results are evaluated in terms of Accuracy, Dice, F1-score, Jaccard, Precision, Sensitivity, Specificity, AUPR, AUROC.
