# AutoTune using Composite Pattern Training

PatMax supports an advanced AutoTune feature that allows you to create PatMax patterns from features in multiple training images. The resulting composite pattern limits the pattern features to those that appear in most (or all) of the training images, and it excludes from the pattern those features that only appear in a few of the image.

Composite PatMax patterns allow you to solve several types of applications that can be difficult when you are limited to pattern training from a single image:

- Applications where no representative image of your part exists.
- Applications where you need to ignore certain features that vary from part to part.
- Applications where a part appears in different backgrounds.
