Overview

gyros-identifier 🍽️

In case you enter a shady restaurant, with suspicious prices and weird plate descriptions, not being able to verify that the food you ordered is a gyros... Fear no more! I made an app able to classify whether an image contains a gyros or not.

The idea stems from the clip of Jian Yang's "Hotdog/Not Hotdog" app from the Silicon Valley series. Here's the clip.

Editor note: The certainty whether this app contributes to society is controversial.

Boring tech details

The pretrained model used was the MLImageClassifier which was fine-tuned using the following custom dataset.

The dataset that was used was a mix of the Food-101 dataset from Kaggle and images of gyros that I downloaded from the internet, mostly from random sources which can be found here.

To split the dataset to Training and Test data I used the dataset_creator.sh bash script. Then I used the CreateML tool to train my model, and finally export it and add it to my XCode project.

Add APP icon and a pretty UI

You could create your logo/launch screen and other stuff on Canvas.

Consult color Palettes for colors that go well with each other.

When you are done with the above, generate your icons for all sizes and platforms.

Add APP icon and a """pretty""" UI #2
Resolve XCode issue with classifier location (irrelevant to the issue but such a trivial change that I should include it)

Add App icon

Change App colors and add a small intro text: "Load a photo or take a picture of your food to find out whether it's a gyros or not!"

Add "clear" button at the bottom of the screen

After the user has loaded an image or taken a photo, there should be a "clear" button that dismisses the used image and returns the app to its default state (the user should see the same things as they would get shown when the app is being loaded the first time).

Improve classifier

Problem

In most case the model classifier gyros images as breakfast_buritto because they look alike. Currently if the model predicts gyros or breakfast_burrito then it will display to the user that the image is a gyros.

Objective

This was an ad-hoc fix to get it working. Improve it so it can separate gyros from breakfast_buritto and the world will laugh less with us.
