+## GPU Acceleration
+
+ODM has support for doing SIFT feature extraction on a GPU, which is about 2x faster CPU on a consumer laptop. To use this feature, you need to use the `opendronemap/odm:gpu` docker image instead of `opendronemap/odm` and you need to pass the `--gpus all` flag to docker:
+
+```
+docker run -ti --rm -v c:/Users/youruser/datasets:/datasets --gpus all opendronemap/odm:gpu --project-path /datasets project
+```
+
+When you run ODM, if the GPU is recognized, in the first few lines of the output log you should notice:
+
+```
+[INFO]    Writing exif overrides
+[INFO]    Maximum photo dimensions: 4000px
+[INFO]    Found GPU device: Intel(R) OpenCL HD Graphics
+[INFO]    Using GPU for extracting SIFT features
+```
+
+The implementation is OpenCL-based, so the acceleration should work with most graphics card (not just NVIDIA).
+
+If you have an NVIDIA card, you can test that docker is recognizing the GPU by running:
+
+```
+docker run --rm --gpus all nvidia/cuda:10.0-base nvidia-smi
+```
+
+If you see an output that looks like this:
+
+```
