| 2. | These algorithms are of great significance for digitized data processing , and supply a gap in spline interpolation 这些算法的开发对于数字化数据处理具有重要意义,也填补了样条插值技术方面的一个空白。 |
| 3. | The 3 - d wire frame and solid images of femoral condyle could be reconstructed when the digitized data were inputted into image processing software of surfacer 9 . 0 对重建图象间隔0 2mm下载,第四军匡大学顾士学位论文以bmp图像格式保存。 |
| 4. | Electronic means refer to the processing and transmission of digitized data , which are transmitted through electronic media such as the internet and designated private network 电子途径是指以电子媒介(例如互联网及专用私人网络等)处理及传送数码数据。 |
| 5. | Based on the digitizing data of the land use map of the taiping st . area in wenling city between 1996 and 2001 , the characteristics of land use changes were analyzed 基于土地利用图的数字化数据,分析了1996 - 2001年温岭市太平街道土地利用的动态变化及其景观生态效应。 |
| 6. | However , it brings up the big problem of too much data while it accommodates the need of the people . this drives it unavoidable to develop some algorithm to compress the digitized data 然而,数字化在满足人们需求的同时,也带来了数据量急剧增加,这样数据的编码压缩就成为了数字化必不可少的关键技术。 |
| 7. | The results show that the correlation between digitized coordinates is obvious . therefore , in order to evaluate the accuracy of digitized data pertinently , it is necessary to process them by correlation adjustment 计算和分析表明,数字化坐标相关性较强,为合理评价数字化数据的精度,应该采用相关平差方法。 |
| 8. | The correlation of digitized coordinates in cadastral map digitization is analyzed by calculating the coefficients among the grids composed of the digitized coordinates . based on this , the digitized data are adjusted by considering their correlation 通过数字化坐标格网点间相关系数的计算对地籍图数字化坐标的相关性进行了分析,在考虑相关性的基础上对数字化数据进行平差处理。 |
| 9. | It is necessary to explore methods to find out interpolation points for processing of substantive and dense digitized data in an automatic manner . this dissertation presents two algorithms called as " quintic - curve - method " and " sixtic - curve - method " which are applied to automatically select nodes for quintic spline interpolation ( 3 )针对大量稠密数字化数据五次样条插值的需要,开发了两种插值节点自动选择算法:五次曲线法和六次曲线法。 |
