# Line Features Finder

This UI controller allows the configuration of multiple line feature finders (for example, line finders). When executed in a sequence, this block behind runs the configured finders on its input images and outputs a list of the found lines and graphics.

Line Features Finder UI consists of four areas: Images, Main Display, Finders, and Details.

### Images

This area lists out all available images for feature finding. The number of images is the same with the image input pins of bonded Line Feature Finder block inside the program. Images are visible on this UI only when there are valid images fed into that block. If not, this area appears as blank and no further operations can be done.

### Main Display

By clicking one of the images, the main display area will show the selected image in larger scale.

### Finders

The finder area maintains all finders that are used to find features. If a finder locates feature using only one input image, that finder should be added under the corresponding camera icon. Otherwise, it should be added under “Multi Camera Finders” category.

There are several buttons allow user to create/edit/modify finders.

- New: Create a new finder such as Line Finder, or Custom ToolBlock Line Finder

- Edit: Edit the selected finder(rename, copy, delete or edit)

- Run: Run the selected finder for user to check the result.

- Features: Rename features found by finders. This function can also be used to pair features. For example, in assembly applications where Paired Features mode is used, features between two parts need to be paired using the same feature names.

### Details

Details area is used to set parameters for selected finder.
