We present a drift-free pose estimation scheme for rigid body and its supporting platform by fusing only two gyroscopes and the relative complementary measurements. The fusion design not only provides robust relative attitude estimation between the rigid body and the platform, but also is capable of identifying partial global absolute attitudes without capturing any absolute attitude information....
In this paper, we focus on the problem of parameter identification in a class of linear system, where system parameter (SP) is nonlinearly coupled in dynamic transition matrix (DTM), such as the well-known maneuvering target tracking with unknown turn rate. By regarding these elements nonlinearly parameterized by SP in DTM as a group of new multiplicative parameters (MP) linearly coupled with system...
With application of the structural equation modeling, the weights of criteria and indicators of evaluation index system of brownfield redevelopment project are assigned by calculating the factor loading of the model. The fit index of the model, such as RMSEA (Root Mean Square of Approximate Error), IFI (Incremental Fit Index), CFI (Relative Fit Index), and NNFI (Non-standard Fitting Index) are tested...
Chang detection is one of the most important research issues in the field of video processing. This paper presents an adaptive method of objects and shadows detection in video streams based on the HSI color space. Bi-models of background is set up via the minimum, the maximum and the largest interframe absolute difference of per static pixel, which are adaptively updated by synthesizing pixel level,...
