Exercise

How many dominant colors?

We have loaded the following image using the imread() function of the image class of matplotlib.

The RGB values are stored in a data frame, batman_df. The RGB values have been standardized used the whiten() function, stored in columns, scaled_red, scaled_blue and scaled_green.

Construct an elbow plot with the data frame. How many dominant colors are present?

Instructions

100 XP

Create a list of distortions based on each value in num_clusters by running the kmeans() function.
Create a data frame elbow_plot with the lists: num_clusters and distortions.
Plot the data with seaborn's .lineplot() method with num_clusters on the x-axis and distortions on the y-axis.
