This paper aims to study the problem of spoofing attack detection for facial recognition systems. Real faces and falsified faces present in front of a security system (phone's camera in our case) have differences of micro-textures on their surface, which are exploited to discriminate face spoofing images. Our method exploits the statistic behavior of the distribution of noise's local variances, which...
A new descriptor called Multi-modal Binary Patterns (MMBP) is proposed for face recognition. It balances well important requirements for real-world applications, including the robustness, discriminative power, and the low computational cost. The proposed algorithm has several desirable properties: 1) it captures information from face image in any direction as it is oriented feature, 2) being a spatial...
A flexible hardware accelerator for full-search vector quantization (VQ) has been developed as a component for a system on a programmable chip (SoPC) to use in real- time image compression and recognition applications. In the system, the number of elements for each codeword and the number of codewords in the system can be changed easily for different applications with the use of an embedded CPU. The...
