摘要:

介绍了三种用于人脸呈现攻击检测的鉴别表示方法。首先,我们设计了一个描述符称为空间金字塔编码微纹理(SPMT)特征来描述局部外观信息。其次,我们利用SSD,这是一个深度学习框架的检测,挖掘上下文线索和进行端到端的人脸呈现攻击检测。最后,我们设计了一个模板人脸匹配双目深度(TFBD)特征来描述真实和虚假人脸的立体结构。为了更准确地检测呈现攻击,我们还设计了两种呈现组合。首先,我们提出了一个决策层级联策略,结合SPMT和SSD。其次,我们使用一个简单的分数融合策略,结合人脸结构线索(TFBD)和局部微观纹理特征(SPMT)。为了证明我们设计的有效性,我们在三个公共数据集上评估了SPMT和SSD的表示组合,其性能优于所有其他最先进的方法。此外,我们评估了我们的数据集上的SPMT和TFBD的表示组合,也取得了优异的性能。

英文摘要:

Three discriminative representations for face presentation attack detection are introduced in this paper. Firstly we design a descriptor called spatial pyramid coding micro-texture (SPMT) feature to characterize local appearance information. Secondly we utilize the SSD, which is a deep learning framework for detection, to excavate context cues and conduct end-to-end face presentation attack detection. Finally we design a descriptor called template face matched binocular depth (TFBD) feature to characterize stereo structures of real and fake faces. For accurate presentation attack detection, we also design two kinds of representation combinations. Firstly, we propose a decision-level cascade strategy to combine SPMT with SSD. Secondly, we use a simple score fusion strategy to combine face structure cues (TFBD) with local micro-texture features (SPMT). To demonstrate the effectiveness of our design, we evaluate the representation combination of SPMT and SSD on three public datasets, which outperforms all other state-of-the-art methods. In addition, we evaluate the representation combination of SPMT and TFBD on our dataset and excellent performance is also achieved.
