As before, the underlying memory isn't copied and Numpy will access it directly - so if you change the data in-place through Numpy, it will be changed in the underlying `cudaImage` as well. For an example of using `cudaToNumpy()`, see the [`cuda-to-numpy.py`](https://github.com/dusty-nv/jetson-utils/blob/master/python/examples/cuda-to-numpy.py) sample from jetson-utils.

Note that OpenCV expects images in BGR colorspace, so if you plan on using the image with OpenCV, you should call [`cudaConvertColor()`](#color-conversion) first to convert it from RGB to BGR (see [`cuda-to-cv.py`](https://github.com/dusty-nv/jetson-utils/blob/master/python/examples/cuda-to-cv.py) for an example of this).
