Background The goal of ontology matching is to identify correspondences between entities from different yet overlapping ontologies so as to facilitate semantic integration, reuse and interoperability. As a well developed mathematical model for analyzing individuals and structuring concepts, Formal Concept Analysis (FCA) has been applied to ontology matching (OM) tasks since the beginning of OM research,...
The segmentation of human hand is still challenged by its complex geometry and similar optical characteristics with other parts of human body. This paper presents an improved strategy for hand segmentation using the randomized decision forest framework based on depth images. In the proposed method, a new depth feature derived from the central point of hand structure, is induced to strengthen the ability...
In this paper, we propose a novel algorithm for the separation of speech mixtures using two-microphone recordings, based on the combination of improved independent component analysis (ICA) and ideal binary mask (IBM). The improved FastICA algorithm reduce the number of Jacobian matrix, significantly reduce numbers of the convergence of the iteration. The basic signals are afterwards improved by the...
