    Depth Evaluation Example Tools for Azure Kinect DK.
 
-   These tools enable developers to collect depth and color images from a Azure Kinect device (`collect`), convert mkv files to images (`mkv2images`), evaluate the depth bias (`depth_eval`), and evaluate the transformation re-projection error between sensors (`transformation_eval`).
+   These tools enable developers to collect depth and color images from a Azure Kinect device using the `collect` and `mkv2images` tools, or from any camera as long as the data can be converted to `mkv` format. Developers can then evaluate the depth bias and evaluate the transformation re-projection error between sensors using the `depth_eval` and `transformation_eval` tools.
