Image segmentation consists of partitioning an image into different regions that share certain characteristics. The ability of a machine learning model to classify or label an image into its respective class with the help of learned features from hundreds of images is called as Image Classification. A new post about maps (with improved examples!) can be found here. pyplot as plt from skimage import data from skimage import filters from skimage import exposure camera = data. One of the important parameters used for Glaucoma screening in the cup-to-disc ratio (CDR), which requires accurate segmentation of optic cup and disc.
