BiteSight

BiteSight is an advanced nutrition tracking application designed to revolutionize how users monitor their diet. Unlike traditional calorie counters that rely solely on manual entry, BiteSight leverages Augmented Reality (AR) and Machine Learning (ML) to estimate food portion sizes and identify dishes directly through your smartphone camera.

Features

• Smart Food Scanning: Utilizes ARCore Depth API to measure food volume and TensorFlow Lite for image classification to identify foods instantly.
• Comprehensive Dashboard: Real-time visualization of your daily caloric intake and macronutrients (Protein, Carbs, Fats).
• Progress Tracking: Visual indicators for daily goals and weekly streaks.
• Meal History: Log and review past meals to stay consistent with your dietary habits.
• Local Storage: All data is securely stored on your device using Room Database.
• Hybrid UI: A modern interface built with a mix of XML Views and Jetpack Compose.

Tech Stack

• Language: Kotlin
• Architecture: MVVM (Model-View-ViewModel)
• UI: Android Views (XML), Jetpack Compose, Material Design 3, MPAndroidChart
• Augmented Reality: Google ARCore (Depth API required)
• Computer Vision & ML:
  • CameraX
  • TensorFlow Lite
• Persistence: Room Persistence Library

Hardware Requirements

To use the core scanning features of BiteSight, you need a physical Android device with specific capabilities. Simulators/Emulators will not work for the AR features.

1. Android Device: Running Android 8.0 (Oreo) or later (Min SDK 26).
2. ARCore Support: The device must be on the list of ARCore supported devices.
3. Depth API Support: The device must support the ARCore Depth API to accurately calculate food volume from the camera feed.

How to Run
