3D Caricature Dataset

You can download the 3D caricature dataset we constructed via Google Drive, or Baidu Drive with password: 0nk6. The 3D caricature dataset contains 7,800 2D caricatures, 2D landmarks and 3D meshes. We also attach the scipts for visualization.

Comparison with us

If you want to do some comparison with our method, you can download a testset here Google Drive, or Baidu Drive with password: 4nvs. It includes 2D caricatures, groundtruth 68 landmarks, 68 landmarks detected by our method and 3D meshes recovered by our method.

Prerequisites and Installation

• Python 3.7
• Pytorch 1.4.0
• opencv-python 3.4.2

Test with Pretrained Model

Within

./CaricatureFace

bash
    bash test.sh

Note: Input images must be preprocessed - crop the whole face roughly and resize to size (224, 224).

Recover 3D faces
