“…To give an idea of the variety of uses, mixture models have been used for image restoration (e.g. Niknejad et al, 2015), for image registration (Gerogiannis et al, 2009), visual tracking (Karavasilis et al, 2012), image retrieval (Beecks et al, 2015), texture modelling (Blanchet & Forbes, 2008), classification (Bouveyron et al, 2007) and sensor fusion (Gebru et al, 2016), to name only a few of the relevant papers. However, the most typical and direct use 397 relates to image segmentation which can be recast straightforwardly into a clustering task.…”
