"Web7 jul. 2014 · In order to cluster our pixel intensities, we need to reshape our image on Line 27. This line of code simply takes a (M, N, 3) image, ( M x N pixels, with three components per pixel) and reshapes it into a (M x N, 3) feature vector. This reshaping is important since k-means assumes a two dimensional array, rather than a three dimensional image. " - Clustering k means c++
