kNN for image classification

In this video I explain how kNN (k Nearest Neighbors) algorithm works for image classification. We vary the parameter max distance of neighbors to be classified (from 1 to 100), in order to show the evolution of the classification. I selected 9 samples for 3 patterns (bare soil, urban areas, vegetation) and used k=3. I provide one animation of the scatterplot in 3 visible spectral bands of a CBERS satellite image (available at https://github.com/tkorting/remote-se.... The source code used to create the animations is available at https://github.com/tkorting/youtube/t... The slides are available at https://prezi.com/bf7r0vaasqim/?utm_c...
