FaceHunter: A multi-task convolutional neural network based face detector

In this paper, we propose a new multi-task Convolutional Neural Network (CNN) based face detector, which is named FaceHunter for simplicity. The main idea is to make the face detector achieve a high detection accuracy and obtain much reliable face boxes. Reliable face boxes output will be much helpful for further face image analysis. To reach this goal, we design a deep CNN network with a multi-task loss, i.e., one is for discriminating face and non-face, and another is for face box regression. An adaptive pooling layer is added before full connection to make the network adaptive to variable candidate proposals, and the truncated SVD is applied to compress the parameters of the fully connected layers. To further speed up the detector, the convolutional feature map is directly used to generate the candidate proposals by using Region Proposal Network (RPN). The proposed FaceHunter is evaluated on the AFW dataset, FDDB dataset and Pascal Faces respectively, and extensive experiments demonstrate its powerful performance against several state-of-the-art detectors.     

Particle filtering with analytically guided sampling

Particle filtering (PF) is a popular nonlinear estimation technique and has been widely used in a variety of applications such as target tracking. Within the PF framework, one critical design choice is the selection of the proposal distribution from which particles are drawn. In this paper, we advocate using as proposal distribution a Gaussian-mixture-based approximation of the posterior probability density function (pdf) after taking into account the most recent measurement. The novelty of our approach is that the parameters of each Gaussian used in the mixture are determined analytically to match the modes of the underlying unknown posterior pdf. As a result, particles are sampled along the most probable regions of the state space, hence reducing the probability of particle depletion. Based on the analytically determined proposal distribution, we introduce a novel PF, termed analytically guided sampling-based PF, which is validated in range-only and bearing-only target tracking.
