This repository is code for our paper Face Template Protection Through Residual Learning Based Error-Correcting Codes.

Introduction

This code aims to implement a face template protection technique by using residual learning, which maps the facial images into low-density parity-check (LDPC) codewords. This implementation is based on PyTorch. In this paper, we use the LDPC coding algorithm developed by Radford M. Neal. The trained CNN model on extended Yale Face B with d = 256 can be downloaded.
