Main code of [**CVPR2020 paper "Searching Central Difference Convolutional Networks for Face Anti-Spoofing"**  ](https://arxiv.org/pdf/2003.04092v1.pdf) 

------

Based on the **Central Difference Convolution (CDC)** and **Contrastive Depth Loss (CDL)**, we achieved

**1st Place** in ChaLearn Multi-Modal Face Anti-spoofing Attack Detection Challenge @CVPR2020


**2nd Place** in ChaLearn Single-Modal(RGB) Face Anti-spoofing Attack Detection Challenge @CVPR2020
