Digital Surface Models (DSMs) generated from airborne laser-scanning or stereo satellite images provide a very useful source of information for building orientation estimation. However, due to the high complexity of the building structure, it is hardly to get the details of the building boundary information. In this paper, a new orientation estimation method is proposed, which merge the edge information...
In this paper, the Potential Function Agglomeration Clustering (PFAC) algorithm has been proposed for estimating the mixing matrix in underdetermined Sparse Component Analysis (SCA), wherein the number of mixtures is less than the number of the sources. In contrast to many existing SCA methods, the PFAC algorithm can accurate estimate the number of sources and the mixing matrix. The algorithm also...
