Face Anti-Spoofing Using Multi-Branch CNN

We propose a face classification system based on deep learning algorithm. This system is capable of distinguishing real and fake faces from RGB images taken by a normal camera. To do that, we have built a system composed of 4 parts: RGB image processing, HSV image processing, YCrCb image processing, and classification. In order to achieve optimal processing performance, we include encoder and decoder structure models, which eliminate unnecessary components and help the model focus only on the components it gives. Most importantly, this structure helps reduce the complexity of the model. In addition, we have applied a number of special tweaks to the training data. Experimental results indicate that our system gives very good results on the public database.
