A Large-Scale Benchmark for Food Image Segmentation

By Xiongwei Wu, Xin Fu, Ying Liu, Ee-Peng Lim, Steven C.H. Hoi, Qianru Sun.

Introduction

We build a new food image dataset FoodSeg103 containing 7,118 images. We annotate these images with 104 ingredient classes and each image has an average of 6 ingredient labels and pixel-wise masks. In addition, we propose a multi-modality pre-training approach called ReLeM that explicitly equips a segmentation model with rich and semantic food knowledge.

In this software, we use three popular semantic segmentation methods (i.e., Dilated Convolution based, Feature Pyramid based, and Vision Transformer based) as baselines, and evaluate them as well as ReLeM on our new datasets. We believe that the FoodSeg103 and the pre-trained models using ReLeM can serve as a benchmark to facilitate future works on fine-grained food image understanding.

[1] We do not include the implementation of swin in this software. You can use the official implementation based on our provided models.
[2] We use Step-wise learning policy to train PVT model since we found this policy can yield higher performance, and for other baselines we adopt the default settings.
[3] We use Recipe1M to train ReLeM-PVT-S while other ReLeM models are trained with Recipe1M+ due to time limitation.

Train & Test

Train script:

 CUDA_VISIBLE_DEVICES=0,1,2,3  python -m torch.distributed.launch --nproc_per_node=4 --master_port=${PORT:-300}    tools/train.py --config [config]  --work-dir [work-dir]  --launcher pytorch

Exmaple:

 CUDA_VISIBLE_DEVICES=0,1,2,3  python -m torch.distributed.launch --nproc_per_node=4 --master_port=${PORT:-300}    tools/train.py --config configs/foodnet/SETR_Naive_768x768_80k_base_RM.py  --work-dir  checkpoints/SETR_Naive_ReLeM  --launcher pytorch

Test script:

 CUDA_VISIBLE_DEVICES=0,1,2,3  python  -m torch.distributed.launch --nproc_per_node=4  --master_port=${PORT:-999} tools/test.py  [config]   [weights]  --launcher pytorch --eval mIoU

Example:

 CUDA_VISIBLE_DEVICES=0,1,2,3  python  -m torch.distributed.launch --nproc_per_node=4  --master_port=${PORT:-999} tools/test.py  checkpoints/SETR_Naive_ReLeM/SETR_Naive_768x768_80k_base_RM.py   checkpoints/SETR_Naive_ReLeM/iter_80000.pth  --launcher pytorch --eval mIoU

ReLeM

We train recipe information based on the implementation of im2recipe with small modifications, which is trained on Recipe1M+ dataset (test images of FoodSeg103 are removed). I may upload the lmdb file later due to the huge datasize (>35G).

It takes about 2~3 weeks to train a ReLeM ViT-Base model with 8 Tesla-V100 cards, so I strongly recommend you use my pre-trained models(link).
