Tracking the Millenium Falcon

Images and annotations taken from - https://github.com/bourdakos1/Custom-Object-Detection

Images consists of frames taken from a clip from Star Wars: The Force Awakens.

Annotations are present for each frame and have the same name as the image name. You can find the example to train a model in python and node, by updating the api-key and model id in corresponding file. There is also a pre-processed json annotations folder that are ready payload for nanonets api.

Build an Object Detector for the Millenium Falcon

Note: Make sure you have python and pip installed on your system if you don't visit Python pip

Step 1: Clone the Repo, Install dependencies

git clone https://github.com/NanoNets/object-detection-sample-python.git
cd object-detection-sample-python
sudo pip install requests tqdm

Step 2: Get your free API Key

Get your free API Key from http://app.nanonets.com/#/keys

Step 3: Set the API key as an Environment Variable

export NANONETS_API_KEY=YOUR_API_KEY_GOES_HERE

Step 4: Create a New Model

python ./code/create-model.py

_Note: This generates a MODEL_ID that you need for the next step

Step 5: Add Model Id as Environment Variable

export NANONETS_MODEL_ID=YOUR_MODEL_ID

_Note: you will get YOUR_MODEL_ID from the previous step

Step 6: Upload the Training Data

The training data is found in images (image files) and annotations (annotations for the image files)

python ./code/upload-training.py

Step 7: Train Model

Once the Images have been uploaded, begin training the Model

python ./code/train-model.py

Step 8: Get Model State

The model takes ~2 hours to train. You will get an email once the model is trained. In the meanwhile you check the state of the model

python ./code/model-state.py

Step 9: Make Prediction

Once the model is trained. You can make predictions using the model

python ./code/prediction.py PATH_TO_YOUR_IMAGE.jpg

Sample Usage:

python ./code/prediction.py ./images/videoplayback0051.jpg

Note the python sample uses the converted json instead of the xml payload for convenience purposes, hence it has no dependencies.
