FoodSAM: Any Food Segmentation

This is the official PyTorch implementation of our paper: FoodSAM: Any Food Segmentation.

Segment anything Model(SAM) demonstrates significant performance on various segmentation benchmarks, showcasing its impressing zero-shot transfer capabilities on 23 diverse segmentation datasets. However, SAM lacks the class-specific information for each mask. To address the above limitation and explore the zero-shot capability of the SAM for food image segmentation, we propose a novel framework, called FoodSAM. This innovative approach integrates the coarse semantic mask with SAM-generated masks to enhance semantic segmentation quality. Besides, it can perform instance segmentation on food images. Furthermore, FoodSAM extends its zero-shot capability to encompass panoptic segmentation by incorporating an object detector, which renders FoodSAM to effectively capture non-food object information. Remarkably, this pioneering framework stands as the first-ever work to achieve instance, panoptic, and promptable segmentation on food images.

[Arxiv] [Project] [IEEE TMM]

FoodSAM contains three basic models: SAM, semantic segmenter, and object detector. SAM generates many class-agnostic binary masks, the semantic segmenter provides food category labels via mask-category match, and the object detector provides the non-food class for background masks. It then enhances the semantic mask via merge strategy and produces instance and panoptic results. Moreover, a seamless prompt-prior selection is integrated into the object detector to achieve promptable segmentation.

<a name="GettingStarted"></a>Getting Started

Demo shell

You can run the model for semantic and panoptic segmentation in a few command lines.

semantic segmentation:

# semantic segmentation for one img
python FoodSAM/semantic.py --img_path <path/to/img> --output <path/to/output> 

# semantic segmentation for one folder
python FoodSAM/semantic.py --data_root <path/to/folder> --output <path/to/output>

panoptic segmentation:

# panoptic segmentation for one img
python FoodSAM/panoptic.py --img_path <path/to/img> --output <path/to/output>

# panoptic segmentation for one folder
python FoodSAM/panoptic.py --data_root <path/to/folder> --output <path/to/output>

Evaluation shell

Furthermore, by setting args.eval to true, the model can output the semantic masks and evaluate the metrics. Here are examples of semantic segmentation and panoptic segmentation on the FoodSeg103 dataset:

python FoodSAM/semantic.py --data_root dataset/FoodSeg103/Images --output Output/Semantic_Results --eval 

python FoodSAM/panoptic.py --data_root dataset/FoodSeg103/Images --output Output/Panoptic_Results
