segment an image from the XCT dataset of Al-Zn solidification using GIMP • In supervised machine learning, image- segmentation pairs are used for training Segmentation steps • Use the 852x852 pixel XCT the segmentation • Set the Opacity to 100 • File –> Export As… • The naming convention in machine learning is to keep the file name and add “_L” to signify that this is a labeled image • Name the segmentation

selection channel in all its glorious detail by toggling the QuickMask button. A large component of learning how to use GIMP effectively is acquiring the art of making good selections—selections that contain [GIMP-DEV-PLUGIN]. GIMP is a complex program, but the development team has made strenuous efforts to flatten the learning curve for plugin writing: there are good instructions and examples, and the main library that plugins plugins use to interface with GIMP (called ‘libgimp’) has a well-documented API.

Script-Fu. The scripts that come with Gimp can be quite useful, but they can also serve as models for learning Script-Fu, or at least as a framework and source of modification when you make your own script. Perl, you will probably be able to use Perl-Fu right away. However, the tutorial doesn’t cover “learning Perl.” That is a vast topic, and it’s simply beyond the scope of this book; but we will give you
