HSIFoodIngr-64: a dataset for hyperspectral food-related studies

This is a new food image dataset HSIFoodIngr-64 containing 3,389 pairs of HSI and RGB images with 21 dish classes and 64 ingredient categories. It is the first HSI based food mage dataset, of which all images are labeled with dish-level and ingredient-level annotations and corresponding pixel-wise ingredient masks. Therefore, our dataset can be applicable for different food-centric tasks.
