Pose for Everything: Towards Category-Agnostic Pose Estimation
[Lumin Xu*, Sheng Jin*, Wang Zeng, Wentao Liu, Chen Qian, Wanli Ouyang, Ping Luo, and Xiaogang Wang]

Existing works on 2D pose estimation mainly focus on a certain category, e.g. human, animal, and vehicle. However, there are lots of application scenarios that require detecting the poses/keypoints of the unseen class of objects. In this paper, we introduce the task of CategoryAgnostic Pose Estimation (CAPE), which aims to create a pose estimation model capable of detecting the pose of any class of object given only a few samples with keypoint definition. To achieve this goal, we formulate the pose estimation problem as a keypoint matching problem and design a novel CAPE framework, termed POse Matching Network (POMNet). A transformer-based Keypoint Interaction Module (KIM) is proposed to capture both the interactions among different keypoints and the relationship between the support and query images. We also introduce Multi-category Pose (MP-100) dataset, which is a 2D pose dataset of 100 object categories containing over 20K instances and is well-designed for developing CAPE algorithms. Experiments show that our method outperforms other baseline approaches by a large margin. Codes and data are available at https://github.com/luminxu/Pose-for-Everything.

1. Install mmpose.
2. run python setup.py develop.

You can follow the guideline of mmpose.

./tools/dist_train.sh ${CONFIG_FILE} ${GPU_NUM} [optional arguments]

If you can run this code on a cluster managed with slurm, you can use the script slurm_train.sh. (This script also supports single machine training.)

./tools/slurm_train.sh ${PARTITION} ${JOB_NAME} ${CONFIG_FILE} ${WORK_DIR}

Here is an example of using 16 GPUs to train POMNet on the dev partition in a slurm cluster. (Use GPUS_PER_NODE=8 to specify a single slurm cluster node with 8 GPUs, CPUS_PER_TASK=2 to use 2 cpus per task. Assume that Test is a valid ${PARTITION} name.)

GPUS=16 GPUS_PER_NODE=8 CPUS_PER_TASK=2 ./tools/slurm_train.sh Test pomnet \
  configs/mp100/pomnet/pomnet_mp100_split1_256x256_1shot.py \
  work_dirs/pomnet_mp100_split1_256x256_1shot

1. The dataset is only for non-commercial research purposes.
2. All images of the MP-100 dataset are from existing datasets (COCO, 300W, AFLW, OneHand10K, DeepFashion2, AP-10K, MacaquePose, Vinegar Fly, Desert Locust, CUB-200, CarFusion, AnimalWeb, Keypoint-5), which are not our property. We are not responsible for the content nor the meaning of these images.
3. We provide the annotations for training and testing. However, for legal reasons, we do not host the images. Please follow the guidance to prepare MP-100 dataset.
