### A new out of the box ML package

The **Signature Comparison** ML Package has been released in Public Preview. This is a new out of the box ML package designed for comparing signatures and it can be found under **UiPath® Image Analysis**.

A signature can appear in various documents, such as forms, checks, and loan documents, and the ability to extract a signature from a document and compare it with a reference signature in another document or in a customer’s database is critical to automate complex document processing workflows.
