Electronic component detection system server for: Nazar App
Tensorflow image classifier with a rest api server to fetch the response from the picture taken using Nazar Application (but lacks HTML UI and only response fetch)
You can use the repository to train yaour dataset using the script and then use the classify.py file to classify the images along with fetching Octopart descriptions for identified components.
Clone the source locally:
$ git clone https://github.com/aryaminus/nazar-server/
$ cd nazar
Install all dependencies of this project
$ pip install -r requirements.txt
You are okay to execute python script now !
By default, where you have cloned the repository you have a tf_files/data. This is where the magic begins, you need to gather enough image to create a dataset of several collections. Yes you can not do just one dataset.
You should have something like that :
├── classify.py
├── requierments.txt
├── retrain.py
├── tf_files
│ ├── data
│ │ ├── register
│ │ │ ├── 00.jpeg
│ │ │ ├── 01.jpeg
│ │ │ ├── 02.jpeg
│ │ │ ├── 03.jpeg
│ │ │ ...
│ │ └── capacitor
│ │ ├── 00.jpeg
│ │ ├── 01.jpeg
│ │ ├── 02.jpeg
│ │ ...
└── train_data.sh
If you have already some dataset to another folder you can edit variable in the train_data.sh :
WORKING_DIR="tf_files"
BOTTLENECK_DIR="$WORKING_DIR/bottlenecks"
STEPS=5000
MODEL_DIR="$WORKING_DIR/inception"
OUTPUT_GRAPH="$WORKING_DIR/retrained_graph.pb"
OUTPUT_LABELS="$WORKING_DIR/retrained_labels.txt"
DATA_FOLDER="$WORKING_DIR/data"
SUM_FOLDER="$WORKING_DIR/retrain_logs"
...And in the classify.py
...
WORKING_DIRECTORY="tf_files"
TMP_DIRECTORY = "tmp"
TRAINED_LABELS="%s/retrained_labels.txt" % (WORKING_DIRECTORY)
RETRAINED_GRAPH="%s/retrained_graph.pb" % (WORKING_DIRECTORY)
...Then all is done just run sh train_data.sh
You will see something like that :
INFO:tensorflow:Final test accuracy = 92.31% (N=1000)
INFO:tensorflow:Froze 2 variables.
Converted 2 variables to const ops.
To classify an image you need to run python classify.py in background (with systemctl for instance or screen).
Then to check if you have access to the api just do curl http://0.0.0.:8080/status/.
To check from local server type in terminal :
curl -POST -H "Content-type: application/json" -d
'{
"data": [{
"image64" : "base_64_encoded_textbase_64_encoded_text"
}]
}'
'0.0.0.0:8080/classify_image/'
To check from the heroku server type in terminal :
curl -POST -H "Content-type: application/json" -d
'{
"data": [{
"image64" : "data:image/png;base64,base_64_encoded_text"
}]
}'
'nazar-server.herokuapp.com/classify_image/'
where the given image64 has extra layer of data:image/png;base64, for base_64_encoded_text
