# Experiment 6: K-Means November 27, 2018 ## 1 Description In this exercise, you will use K-means to compress an image by reducing the number of colors it contains. To begin, download data6.zip and storing only the RGB values of the 16 colors present in the image. In this exercise, you will use K-means to reduce the color count to k = 16. That is, you will compute 16 colors as the cluster centroids centroids on a 538x538 image would be time-consuming on a desktop computer, you will instead run K-means on the $ 128 \times 128 $ image bird_small.tiff. Once you have computed the cluster centroids on

This kernel remains active if the web browser window is closed, and the web application to the same kernel. In the dashboard, notebooks with an active kernel have a Shutdown button next to them, whereas notebooks without an active kernel have a Delete button in its place
