Vector map overlay is a core operation in the fields of spatial information processing. To meet the demand of overlay analysis with large scale vector data, this paper proposes a vector map overlay algorithm based on distributed task queue and designs a desirable task structure composed of geometries pair and a task assignment strategy based on spatial location. As well known, data access and load...
Subspace models play an important role in a wide range of signal processing tasks, and this paper explores how the pairwise geometry of subspaces influences the probability of misclassification. When the mismatch between the signal and the model is vanishingly small, the probability of misclassification is determined by the product of the sines of the principal angles between subspaces. When the mismatch...
