A combine-then-adapt (CTA) diffusion proportionate affine projection algorithm (DP APA) is proposed for distributed estimation, which uses gain matrices in the CTA diffusion affine projection algorithm (DAPA) to proportionately adapt the weight vectors of agents in the network. Then, a variable step-size (VSS) is presented for the DPAPA to address the problem of tradeoff between fast convergence rate...
An effective and fast face pose estimation method in video sequence has been proposed based on estimating the relative location of mouth in a face. Firstly, Faces are detected in the first several frames of video sequence. Then the detected face region is being tracked by the CAMShift (Continuously Adaptive Mean Shift) algorithm and an ellipse model is used to locate human face regions and angles...
The traditional algorithm of GNSS orientation using LAMBDA for single frequency receiver, couldnpsilat estimate the integer ambiguity in a little time, sometimes, couldnpsilat find the exact value. Based on the theory of Rough integer mapping, we get a new algorithm for the estimation of integer ambiguity to solve the problems we meet. Searching algorithm with granularity changing could improve the...
This paper examines the performance of three different approaches in estimating the firm parameters of structure models by simulation, including the simultaneous equation system approach, maximum likelihood estimation approach and the iteration approach. The simulation results show that iteration approach has smaller estimation errors than the other two approaches and thus performs the best.
