In this paper, a new algorithm for visualization of high-multidimensional data is described. The algorithm follows several steps. At first, centers representing several categories are selected, and Euclidean distances between these centers are calculated in a high-dimensional space. Then these centers are placed in a 2-dimensional space in such a way that distances in this 2-dimensional space are...
To tackle the problem of lacking auxiliary information while generating the side information, we have proposed a novel spatial aided low delay Wyner-Ziv video coding scheme in which the wavelet transformation is applied to generate the auxiliary information. However, there exists an inefficiency that lowers the coding performance. The inefficiency is that many wavelet coefficients having very small...
A new method of feature recognition based on similarity measure of primitive views is put forward to enhance efficiency of reconstruction of 3D solid mode of mechanical part from engineering drawing and expand its application in this paper, The details of this method include separating three views of single and combined primitive bodies by view loop searching; coding primitive view loops and calculating...
For improving validity and efficiency of 3D reconstruction from 2D engineering drawings, this paper presents a new method of primitive feature recognition based on graphics comparability determining of view loop. Main steps of this method are as follows: Firstly separate three views of single or combined primitive bodies by loop search, and then code view loops of primitive body and calculate graphics...
