How to make a reference image and mask

The easiest way to make a reference image is to use your preferred GIS image tool (like QGIS) to extract a small region from the orthomosaic. To make the mask open the reference image in an image editor and use the pen tool to mark all the desired pixels with red ((255, 0, 0) in RGB).

Run CDC

To run CDC on an orthomosaic, run the following in a terminal window:

CDC path/to/orthomosaic path/to/reference_image path/to/mask_image

Run CDC --help for more information or see the Documentation.
