Abstract
Although automatic faces recognition has shown success for high-quality images under controlled conditions, for videobased recognition it is hard to attain similar levels of performance. We describe in this paper recent advances in a project being undertaken to trial and develop advanced surveillance systems for public safety. In this paper, we propose a local facial feature based framework for both still image and video-based face recognition. The evaluation is performed on a still image dataset LFW and a video sequence dataset MOBIO to compare 4 methods for operation on feature: feature averaging (Avg-Feature), Mutual Subspace Method (MSM), Manifold to Manifold Distance (MMS), and Affine Hull Method (AHM), and 4 methods for operation on distance on 3 different features. The experimental results show thatMulti-region Histogram (MRH) feature ismore discriminative for face recognition compared to Local Binary Patterns (LBP) and raw pixel intensity. Under the limitation on a small number of images available per person, feature averaging ismore reliable than MSM, MMD, and AHM and ismuch faster. Thus, our proposed framework--veraging MRH feature is more suitable for CCTV surveillance systems with constraints on the number of images and the speed of processing.
