The MRI brain scans that we will use for our k-means clustering model have been downloaded from The Cancer Imaging Archive (TCIA), a service that anonymizes and hosts a large archive of medical images of cancer for public download, and that may be found at http://www.cancerimagingarchive.net/.
The MRI scan of our healthy human brain may be found in the GitHub repository accompanying this book, and is called mri-images-data/mri-healthy-brain.png. The MRI scan of the test human brain is called mri-images-data/mri-test-brain.png. We will use both in the following Spark application when training our k-means clustering model and applying it to image segmentation. Let's begin:
The following subsections describe ...
