A real-time system for sign language recognition via hand gestures is proposed in this paper. Hands postures are detected and hand gestures are recognized based on features of hand which are extracted using the Haar-Like features. K-means clustering algorithm is used to reduce the number of ext...

To achieve an insightful clustering of multivariate data, we propose subspace K-means. Its central idea is to model the centroids and cluster residuals in
However, this means your money won't have the opportunity to grow over time. “Depending on the reasons for the distribution, there may be tax or early withdrawal penalties and the distribution itself may also be taxable,” said Allison Brecher, general counsel at New York City-based Vest...
