ECUSTFD — food images with calorie labels

ECUST Food Dataset: 2,978 smartphone photos of 19 food types (top + side views, 25 mm coin as calibration object), with per-object weight/volume measurements and derived calorie labels.

Files

• images/ — original JPEGs (resized <1000px)
• annotations.csv — Pascal VOC annotations: file, object_id, name, xmin, ymin, xmax, ymax
• portions.csv — per food object: sheet, id, type, volume_mm3, weight_g, kcal_per_100g, calories
• food_types.csv — per food type: kcal_per_100g (USDA FDC reference, estimated flags analogs)

calories = weight_g × kcal_per_100g / 100. object_id in annotations joins to id in portions (e.g. apple001).
