NotShark

Something that's not a shark.
That's a shark.

💡 Inspiration

I am sure everyone who has ever watched the TV series Silicon Valley remembers Jian Yang's HotDog/Not HotDog classifier. We thought it would be really cool if we tried to build a shark version of the same for the hackathon. It is modeled after the HotDog app and also has a login screen which involves a meme from the series.

🏡 What it does

When the phone camera is pointed at something while in the app, it classifies that as Shark/Not Shark (Hence the name!).

🔨 How we built it

There are two major components:

The mobile app: For this we used Flutter so that we could build the app for both Android and iOS. To then classify images taken using the camera, we used the tflite library and used it to interface the model and the app.
Shark Classifier: We built an ML model using TensorFlow and Keras that classifies images and tells you whether an image is a shark or not. This is then converted to a TensorFlow Lite model to run on mobile.

🥲 Challenges we ran into

Gathering and organizing the dataset for Sharks and Not Shark objects.
Interfacing the Tensorflow model with the flutter app - omg was this difficult. We had so many problems, and in the end, we managed to retrieve the result using

🏆 Accomplishments that we're proud of

We built the sort of good-looking app in the span of the span of the hackathon, from scratch.
We managed to interface the ML model with the app and finally managed to complete it.
