🍽️ Extended Food-270 Dataset

This dataset is an extended version of the original Food-101 dataset, designed to improve the diversity and representativeness of food image classification models.
It combines the well-known Food-101 dataset with additional custom food images collected and curated by Berker Üveyik to expand the number of classes and enhance the dataset’s real-world applicability.


πŸ“š Overview

  • Base Dataset: Food-101
  • Extended Version: Food-270
  • Total Classes: 270 (101 original + 169 custom classes)
  • Total Images: ~ 229.245
  • Split: 80% training / 20% testing
  • License: CC BY-NC 4.0

🧠 Motivation

The original Food-101 dataset is a landmark benchmark for food recognition tasks, yet it primarily focuses on Western cuisine.
To enhance cultural and dietary diversity, this dataset extends Food-101 by adding 169 new food categories, including homemade, regional, and custom dishes.

These additional categories were carefully curated to:

  • Improve the diversity and generalization capabilities of food classification models.
  • Provide broader representation for non-Western and culturally specific foods.
  • Enable research in nutrition tracking, food recognition, and calorie estimation applications.

This dataset is particularly suitable for:

  • Food classification and computer vision research.
  • Nutrition estimation and smart diet-tracking systems.
  • AI-driven food recognition mobile applications.

  • Train Folder: Contains 80% of the total images for training.
  • Test Folder: Contains 20% of the total images for model evaluation.
  • Each subfolder represents one distinct food class.

βš™οΈ Dataset Creation Process

  1. Data Collection

    • The base 101 food classes were sourced directly from the Food-101 dataset.
    • 169 new classes were manually collected from diverse online sources and personal photography.
  2. Data Cleaning and Curation

    • Duplicate and low-quality images were removed.
    • Labels were verified and organized consistently across classes.
    • Class distributions were balanced as much as possible.
  3. Train/Test Split

    • The dataset was divided with an 80/20 ratio, ensuring that each class maintains the same proportion of samples in both sets.
