The recently proposed triplet Markov fields (TMF) model enhances the nonstationary image prior modeling ability by introducing an auxiliary field. Motivated by the TMF model, we propose a generalized TMF model based on ambiguity label information fusion (ALF-TMF) for synthetic aperture radar (SAR) image segmentation. The redefined auxiliary field in ALF-TMF indicates the dominant direction of local...
Accurate traffic flow forecasting is crucial to the development of intelligent transportation systems (ITS). Based on statistical learning theory, support vector machine (SVM) has better generalization performance and can guarantee global minima for given training data. However, the good generalization performance of SVM highly depends on the construction of kernel function. An effective multi-scale...
Persistent Scatterers for SAR Interferometry (PS-InSAR) tecnique allows monitoring the temporal evolution of a deformation phenomenon at millimeter level, via the generation of mean deformation velocity maps and displacement time series from a data set of acquired SAR images. However, the serious noises of multi-temporal SAR images make the selection of permanent scatters (PSs) difficult. In this...
This paper studies the problem of evaluation index system and weight of index system. Firstly, we define energy efficiency of distribution transformer and discuss the influence of energy efficiency of distribution transformers on distribution network to make the index more general. Secondly, we establish an index system of distribution network for economic evaluation. Thirdly, an improved AHP (Analytic...
In this paper, we solve the multi-item capacitated dynamic lot-sizing problems, where each item faces a series of dynamic demand and in each period, multiple items share limited production resources. The objective is to find the optimal production plan so as to minimize the total cost, including production cost, inventory holding cost, and fixed setup cost. We consider both single-level and multi-level...
