# Shape Training Guidelines

In general, you should observe the same guidelines for training patterns from shape models that you do when training from images. The shapes you supply should uniquely identify the pattern you are looking for, and they should not be confusing when considered in the degrees of freedom you will be enabling.

Some other shape training guidelines you should keep in mind:

- Do not supply shapes with infinite extent (such as lines) for shape training
- Carefully evaluate the granularity limits, as described in the topic Computed Granularity.
