Pattern recognition (PR) based myoelectric hand control has become a research focus in the field of rehabilitative engineer and intelligent control. However, the state of the art method is hardly adopted for clinical use because of signal interfered by shift, fatigue and user-unfriendly of retraining. The aim of this study is to evaluate the performance of different kinds of online algorithms in classifying...
In this paper we proposed a scalable interactive system for fresco deterioration detection by hyper-spectral image data analysis. The system integrates data mining and visualization algorithm and process the hyper-spectral big data from fresco efficiently and conveniently. Firstly, a Geospatial Data Abstraction Library (GDAL) is adapted which provides data reading, image preview and cropping functions,...
This paper proposes a new affine registration algorithm for 2D point matching. It is a two-step iterative registration algorithm by soft weight assignment based on bidirectional distance. At each iteration, the affine transformation is updated by two optimization steps, in which the model data and the test data are matched from each other respectively. By the optimization of registration at separate...
In this paper, we present a unifying approach to specifying and verifying specification-oriented XML constraints. The formal tree model and the XML constraint logic are developed to describe the XML documents and constraints respectively. The XML constraint logic, as an extension of the first order logic, is constructed and interpreted in the framework of our formal tree model, where the node domain...
