Fruits Freshness Classification using Deep Learning Python Project  is a web application, implemented with Python (Flask framework), which uses a convolutional neural network on the back-end to perform fruit classification. The system is able to distinguish 6 classes of fruits: fresh/rotten apples, fresh/rotten oranges and fresh/rotten bananas. The user is able to interact with the app by uploading images or by showing the fruits to the web-camera. The app uses Web Speech API to make the experience more interactive and fun.

Warning! As there’s no fallback class like “a non-fruit object”, please don’t take it personally when the model classifies the photo of you as a rotten banana 😅 (this also applies to any object, that doesn’t belong to the mentioned classes).

Dependencies

For this project, the following tools were used:

1. Tensorflow 2 for building and training the model;
2. Numpy for working with arrays;
3. Matplotlib for visualizing the data;
4. Flask for implementing the server side;
5. HTML5, CSS3, JavaScript (with Web Speech API and particles.js) on the front-end.

The dataset used for training and evaluating the model: Fruits fresh and rotten for classification by Sriram Reddy Kalluri. The obtained model has achieved 99% accuracy on the test set.

The network itself was implemented using transfer learning. The MobileNet V2 model developed at Google was used as a base model for feature extraction from our data. A custom classification layer was added on top and trained separately.

To install and run locally in a production mode:
