# Green Classify Tool – Classification Tags

The Green Classify tool performs classifications of images and/or Views by assigning a classification tag to the image and/or Views.

There are a few ways the tool's classification capabilities can be used:

- It can be used to simply classify an object in an image, such as Part A, Part B, Part C, etc. In addition, it can be used as a gating tool, where it is used prior to other tools performing inspections downstream. For example, the Green Classify tool determines that it is Part B, which has a Red Analyze tool that performs further inspection, whereas if it was Part C, a Blue Locate tool would count features.
- It can be used downstream of a Red Analyze tool to classify the types of defects that were encountered, or after a Blue Locate tool to classify the type of Model that produced a particular View.

With the Green Classify tool, you will generally be using a large Training Image Set. Prior to using the tool, it is recommended to annotate your image files with descriptive names or numbering schemes to help when labeling the images.

You can label the views by specifying a tag, or using a Regular Expression to programmatically enter tags for the images based on the file names of the images.

After the classification tags have been applied, and the tool has been trained, you can review the results to ensure that the tool correctly marked the images.
