Main code of CVPR2020 paper "Searching Central Difference Convolutional Networks for Face Anti-Spoofing"

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

It is just for research purpose, and commercial use is not allowed.
