With high speed input data flow, the algorithm of parallel-decomposition and coefficient-partitioned convolution is proposed to meet the real-time requirement. With the decomposition of the input data and the coefficient sequence, the input data flow from ADC with high sample rate can be slow down; with the partition of the coefficient sequence, the overall convolution process can be partitioned into several sub-convolutions and implementing into multi-chip FPGA hardware platform. The algorithm and design architecture shown in the paper is useful in complicate radar echo signal simulation with broadband coverage and low input-output delay.","PeriodicalId":109229,"journal":{"name":"2008 International Conference on Computer Science and Information Technology","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121478682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, this algorithm divides the image into block images, which are also called sub-images. Then the well-known Fisher method is directly employed to the selecting sub-images obtained from the previous step, and the new lower dimensionality patterns that replace the original patterns are obtained. Finally the recognition results are obtained by the general minimum distance classifier. The ORLface image database is made use of to simulate and the results shows that this method presented in this paper is obviously superior to the traditional Fisher method. And when the training sample is only one, the recognition rate of 90.83 percent is achieved. It is indicate that M-FLDA can not only accelerate recognition speed by reducing dimensionality but also reduce the memory capacity. Finally, the preliminary study of solving facial pose changes is presented.","PeriodicalId":109229,"journal":{"name":"2008 International Conference on Computer Science and Information Technology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122189739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the source images are decomposed by dual tree complex wavelet transform (DT-CWT) respectively. Then, the wavelet coefficients are modeled using the generalized Gaussian distribution (GGD). Saliency measure, the weighted coefficient, is calculated by estimating distribution parameters. The pair of coefficients is fused through weighted average. Finally, the fused coefficients are reconstructed into a single fused image. The quality of the fused image is evaluated by three metric: entropy, mutual information and QAB/F.The experimental results demonstrate that performance of the proposed method is prior to other two fusion approaches for infrared and visible dynamic image sequence.","PeriodicalId":109229,"journal":{"name":"2008 International Conference on Computer Science and Information Technology","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116598168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We represent the model using a scene graph hierarchy and construct continuous hierarchical levels of detail (CHLOD) for each hierarchical node. The CHLOD of a node is computed by a view-dependent simplification method which can support topological structure modification. At run-time, the hierarchy is used for coarse global refinement, and the CHLODs are used for fine local refinement. We have implemented our method on a common PC with standard graphics hardware. Experimental results show that the system can perform interactive rendering of large-scale virtual environments with fine image quality and minimal popping artifacts.","PeriodicalId":109229,"journal":{"name":"2008 International Conference on Computer Science and Information Technology","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122811784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Weights, basis width and central vectors of gauss function are tuned and achieve stable value by iteration until the performance index is less, all of which and activation function are equivalent to projection matrix of cameras, thus calibration of system is accomplished.
