This work presents a study on label noise in medical image segmentation by considering a noise model based on Gaussian field deformations. Such noise is of interest because it yields realistic looking segmentations and because it is unbiased in the sense that the expected …

Thresholding. Thresholding is a method of image segmentation used to create a binary image from gray-scale or color images. A binary image is an image that has only 2 values, usually black and white, meaning pixels have a value of 0 or 255 .
