Mamiko ONO et al. (pp. 1599–1603)
Extraction of the cortex and medulla of the equine ovary. A: Original image. B: Regions with similar colors were grouped by the mean shift method. C: The image was divided into three classes, the background, cortex (white) and medulla (gray), by the k-means method. D: Regions corresponding to the follicles (red) were extracted from the original image. E: A composite image of C and D. The follicles detected within the medulla were regrouped with the cortex.
