This is a simple image classification Flask app trained on the top of Keras API. The trained model (
app/model/model.h5) takes an image (Indian Paper Currency) as an input and predict the class of image from 10, 20, 50, 100, 200, 500, 2000 denomination.
What could be a perfect way to utilize unfortunate lockdown period? Like most of you, I spend my time in cooking, Netflix, coding and reading some latest research papers on weekends. The idea of classifying indian currency struck to me when I was browsing through some research papers. I couldn't find any relevant research paper (and of course dataset!) associated with it. And that led me to collect the images of Indian currency to train a deep learning model using this amazing tool.
This project is divided into two part:
The Code is written in Python 3.7. If you don't have Python installed you can find it here. If you are using a lower version of Python you can upgrade using the pip package, ensuring you have the latest version of pip. To install the required packages and libraries, run this command in the project directory after cloning the repository:
pip install -r requirements.txt
.zshrc file and add the following credentials:
export AWS_ACCESS_KEY="your_aws_access_key" export AWS_SECRET_KEY="your_aws_secret_key" export ICP_BUCKET='your_aws_bucket_name' export ICP_BUCKET_REGION='bucket_region' export ICP_UPLOAD_DIR='bucket_path_to_save_images' export ICP_PRED_DIR='bucket_path_to_save_predictions' export ICP_FLASK_SECRET_KEY='anything_random_but_unique' export SENTRY_INIT='URL_given_by_sentry'
Note: SENTRY_INIT is optional, only if you want to catch exceptions in the app, else comment/remove the dependencies and code associated with sentry in
Since, I don't have a system with Windows OS, here I collected some helpful resource on adding User Environment Variables in Windows.
Attention: Please perform the steps given in these tutorials at your own risk. Please don't mess up with the System Variables. It can potentially damage your PC. You should know what you're doing.
To run the app in a local machine, shoot this command in the project directory:
Set the environment variable on Heroku as mentioned in STEP 1 in the Run section. [Reference]
Our next step would be to follow the instruction given on Heroku Documentation to deploy a web app.
