3.2.1. Mean Shift

The unsupervised learning Mean Shift algorithm is based on clustering and is also applied to digital images [48–51]. This algorithm, transforms the digital image in Figure 4a, passing through surface construction, as shown in Figure 4b, and cluster detection, in a multidimensional space, as in Figure 4c, where the points represent all pixels assigned to a specific cluster.
