Layout Classifier

Concept and Application

Layout classification makes use of the geometrical structure of a document to
determine its class. Ascent Xtrata Pro can automatically learn about the geometrical
structure of a class by analyzing a number of example documents that are
representative of that class.

Documents with completely different layouts can be associated with a single class
provided you have examples of each. Typically, layout classification is used to
identify documents in a batch. But, it can also be utilized to recognize the sender of a
letter if the sender’s document layout is unique. This might be the case for formal
letters or invoices.

Set Up

The Layout Classifier can be inserted into the current project the first time documents
are added to a class and the “Use for layout classification” option is selected from the
list.

The first time you do this, you are asked if you want to add image classification
support to the project. If you click Yes, the Layout Classifier is added to the project.
Once the Layout Classifier has been added to the project, you are no longer asked
this question.

You can freely add or remove documents from the Training Set for each class.

Before the Layout Classifier can be tested, it must be trained with the document in
the training sets. This step extracts the relevant features from all the training images
and stores them inside the project.
