CDC can be a useful tool if you want to locate objects in an image / orthomosaic with a certain color. The tool can be used to go from this input image
To this output image
To learn more about the tool, take a look at the tutorial.
CDC is a python package and can be installed with pip.
pip install CDC
For more advanced installation, please visit the Documentation for more information.
For a tutorial of how to use CDC on a test dataset, please see Tutorial.
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).
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.
For a full list of command line arguments see CLI. For a reference manual, please visit Reference Manual
