Dataset Summary

FoodSeg103 is a large-scale benchmark for food image segmentation. It contains 103 food categories and 7118 images with ingredient level pixel-wise annotations. The dataset is a curated sample from Recipe1M and annotated and refined by human annotators. The dataset is split into 2 subsets: training set, validation set. The training set contains 4983 images and the validation set contains 2135 images.

Data Splits

This dataset only contains two splits. A training split and a validation split with 4983 and 2135 images respectively.

Dataset Creation

Curation Rationale

Select images from a large-scale recipe dataset and annotate them with pixel-wise segmentation masks.

Source Data

The dataset is a curated sample from Recipe1M.

Initial Data Collection and Normalization

After selecting the source of the data two more steps were added before image selection.

Recipe1M contains 1.5k ingredient categoris, but only the top 124 categories were selected + a 'other' category (further became 103).
Images should contain between 2 and 16 ingredients.
Ingredients should be visible and easy to annotate.

Which then resulted in 7118 images.

Annotations

Annotation process

Third party annotators were hired to annotate the images respecting the following guidelines:

Tag ingredients with appropriate categories.
Draw pixel-wise masks for each ingredient.
Ignore tiny regions (even if contains ingredients) with area covering less than 5% of the image.

Refinement process

The refinement process implemented the following steps:

Correct mislabelled ingredients.
Deleting unpopular categories that are assigned to less than 5 images (resulting in 103 categories in the final dataset).
Merging visually similar ingredient categories (e.g. orange and citrus)

Who are the annotators?

A third party company that was not mentioned in the paper.
