After the image is segmented we need to get statistics describing the data for each band within each segment. The tutorial will show you how to use numpy and scipy to get statistics from image segments. Once we have the statistics we can begin to group segments based on the statistics values. This is what will eventually allow us to group, or classify, image segments. Stay tuned for the next tutorial in the object-based image analysis playlist. At the end of this tutorial series (playlist) we will have covered how to go from a downloaded image to a fully classified image.
