This page describes how to use the extension "Blur Registration" in the Orbit 3DM Blur and Erase Production.

As the name says, "Blur Registration" extension makes it possible to blur or to erase parts of an image, in order to hide unwanted elements. It can be used to hide car plate numbers or people faces. The extension is designed to allow very fast processing. For example, in an optimal environment, it is possible to process around 600 images per hour.

The Orbit desktop product Blur and Erase Production does not include the administration procedure "Import Run". In order to be able to blur and erase imagery, the user must have a run previously imported or created by another Orbit product and add it via the Blur Registration extension. 

==== Concepts ====

**Blur**\\
Make one or several parts of an image indistinct, unclear and hazy by reducing the edge content and making the transition from one color to another very smooth.

**Erase**\\
Delete a part or several parts of an image by changing the pixels in that area to a different color. 

**Files & folders**\\
As result, .xml files containing the definition of the blurred areas are created. These files are saved in the same location as the input imagery.

**Open Project**\\
Choose the run to process.

**Start**\\
Start the procedure. By default, the first available image will be opened. Simply find the locations to blur and create the blurring areas by hovering the mouse cursor to the desired locations.

**Search Box**\\
Search for a particular image, by using the name or a part of the name, inside the opened run folder structure. The result of the search will be displayed on Blur Registration Tab.

**Navigation Tools**\\
Tools to navigate through the imagery, by going to previous, next, first or last imagery.

**Blur**\\
Draw a polygon around the area to be blurred, directly on the MM Views. 

**Erase**\\
Draw a polygon around the area to be erased, directly on the MM Views.

==== Workflow ====

  - Choose the project
  - Start the procedure ( choose to blur or erase part of the imagery)
  - Choose the cursor shape
  - Roam through the images and find the ones that need processing
  - Find areas that need to be blurred, like car plates or faces

<note tip>
The .xml files can be physically written on the images using the [[209:desktop_ext:blur_erase|Blur&Erase QC]] tool, or using the procedure [[209:desktop_ext:mapping:manage:imagery|Optimize Imagery]]
