“…Consider the problem of segmenting a micrograph of a material containing multiple thermodynamic phases: A naïve approach for segmentation consists of identifying a threshold on the intensity which will classify the image pixels by phase. More often than not, this approach will fail due to insufficient contrast between the phases, uneven illumination of the sample, surface topology of the sample, noise in the image, etc (McInerney & Terzopoulos, 1999; Despotović et al, 2010; Zhu et al, 2013). Denoising, or some other form of cleanup, will oftentimes be applied to the data in order to remove some of these artifacts before or after segmentation; however, this approach can be resource intensive, is not easily automated, and may only be partially successful (Preethi & Narmadha, 2012; Soni et al, 2014).…”
