Annotated dataset of HepG2 spheroids (YOLO format)

Dataset of birghtfield images of HepG2 spheroids in SP5D culture plates (Kugelmeiers) after 5 days of culture using a custom made inverted microscope with 4X magnification. The dataset consists of 1,395 images with a total of 19,129 labels. Three classes were defined: 0 for 'None', 1 for 'Healthy', 2 for 'Unhealthy'. The labelling was partially manual and partially automated: some spheroids were exposed to a toxic compound and automatically labelled as 'Unhealthy'. The resulting dataset includes 12,599 spheroids labelled as 'Healthy' and 6,530 as 'Unhealthy'. The dataset was partitioned into three sets for the training of a YOLO network: 70% images for training, 15% for testing and 15% for validation.
