Annotation of whole slide images (WSI) using the Computer Vision Annotation Tool (CVAT). This figure illustrates the CVAT interface used for the annotation of ovarian structures for image analysis. The interface displays an image of an ovary section with annotated regions highlited by colored boxes. The yellow box indicated the area corresponding to the corpus luteum. The blue box delineates an antral follicle lacking a visible nucleus. The pink box represented an antral follicle with a discernible nucleus.
