DACov: A Deeper Analysis of Data Augmentation on the Computed Tomography Segmentation Problem

1 code implementation10 Mar 2023 Bruno A. Krinski, Daniel V. Ruiz, Rayson Laroca, Eduardo Todt

Our findings show that GAN-based techniques and spatial-level transformations are the most promising for improving the learning of deep models on this problem, with the StarGANv2 + F with a probability of 0. 3 achieving the highest F-score value on the Ricord1a dataset in the unified training strategy.
