“…A variety of neural net and other architectures have been explored to improve detection and classification accuracy and expand generalizability to new types of images. Several deep learning architectures developed for natural images have been adapted for marker detection in images of cells including Fully Convolutional Networks (FCNs) (Lux and Matula, 2020), Visual Geometry Group (VGG16) (Wang et al, 2019;Shahzad M et al, 2020), Residual Networks (ResNets) (Lee and Jeong, 2020), UNet (Al-Kofahi et al, 2018;McQuin et al, 2018;Schmidt et al, 2018;Wen et al, 2018;Vu et al, 2019;Horwath et al, 2020;Lugagne, Lin and Dunlop, 2020), and Mask R-CNN (Kromp et al, 2019;Vuola, Akram andKannala, 2019, 2019;Korfhage et al, 2020;Liu et al, 2020;Masubuchi et al, 2020). In classical image analysis, advances in methodology commonly involve the development of new algorithms; any changes in parameter settings needed to accommodate new data are regarded as project-specific details.…”
