In this work, we introduce GazePose, a novel unified framework with an that improves eye contact detection by aggregating pose-related prior knowledge via a crossattention mechanism. To our knowledge, GazePose is the first framework to integrate 3D head pose and 2D facial landmarks as cues to obtain more accurate and robust representations for eye contact detection.
Model | Ego4D (mAP) | url |
---|---|---|
GazePose | 76.29 | model |
Baseline | 71.92 | model |
You should prepare your data just as Ego4D. Specially, your structure should be like this:
data/
* csv/
* json/
* split/
* result_LAM/
* json_original/
* video_imgs/
* face_imgs/
* uid
* trackid
* face_xxxxx.jpg
It should be noticed that pictures in face_imgs are preprocessed from video_imgs. We simply crop the face bbox and resize every face as (224,224), re-organizing them as uid/trackid/face_xxxxx.jpg, where xxxxx means its frameid. You can see the detail in dataset/data_loader.py.
And for the annations of headpose, you can directly use model in deep-head-pose and run it on face crops. We use 'uid-trackid-frameid' as keys in our headpose annations. Please refer to dataset/data_loader.py. And we provide the code to predict head pose for Ego4D in headpose.py.
For the annations of facial landmarks, we use model in mediapipe and run it on face crops. And we provide the code to predict landmarks for Ego4D in meshp.py.
For the Gaussian Temporal Dropout, we can obtain images' quality through vartool.py and also can obtain the distribution for each split. We release our filter JSON FILE for train set train_filter. Please download it and change the value of "filter_file" in config.py.
Please use above code and files to obtain the prior json files, put them in the same directory and change the value "prior_path" in config.py.
Specify the arguments listed in common/config.py if you want to customize the training.
You can use:
bash posetrain.sh
To simply start a training process, it will run GazePose training process on your first GPU.
For the baseline, you can use:
bash basetrain.sh
You can use:
bash poseval.sh
bash baseval.sh
To simply start a inference process, specific --checkpoint [your checkpoint]
to choose your checkpoint for evaluate on GazePose or Baseline. We provide a pretrained checkpoint for GazePose model.
The argument --val
will start a evaluate on validation dataset and the argument --eval
will start a evaluate on test dataset.
Specially, the test set of Ego4D should be placed as follows:
videos_challenge/
* uid
...
GazePose/
* data
...
Or you can also specified the "test_path" in config.py.
