According to the actual requirements of telecommunications enterprises customer segmentation, in this paper an improved K-Means algorithm was introduced. The algorithm was used to initialize cluster center in the cluster analysis phase of Data Mining technology. The experimental results proved that the novel algorithm has greater improvement than the original one in efficiency and accuracy. The results...
In 3D video applications, the virtual view is generally rendered by the compressed texture and depth. The texture and depth compression with different bit-rate overheads can lead to different virtual view rendering qualities. In this paper, we analyze the compression-induced rendering distortion for the virtual view. Based on the 3D warping principle, we first address how the texture and depth compression...
We report on a reflection microscope that operates at 13.2-nm wavelength with a spatial resolution of 55 plusmn 3 nm. The microscope uses a table-top EUV laser to acquire images of photolithography masks in 20 seconds.
