家庭和一般单位养苏铁,时间长了,常会碰到这样的问题,花盆越换越大,而苏铁也一年比一年高,到后来,没地方放不说,就是想搬一下也不容易。盆内根系紧密,盆土坚硬,导致生长不良,失去其固有的观赏价值。为解决这一问题,我们在前后三年的时间内,对自己的两盆苏铁进行截干养桩、打头扦插,收到了很好的更新复壮效 相似文献

基于.net 2.0三层架构的青岛市数字城建档案馆 总被引:1,自引:2,他引:1
为了提高城市建设档案的管理水平和利用率,为数字城市打下良好的基础,基于.ner2.0组件技术,采用反射工厂模式设计数据访问层,实现了基于分层架构的"青岛市数字城建档案馆"系统.系统综合运用.net framework2.0、Asp.net2.0、A5p.net Aiax、水晶报表等技术,借助GIS实现二维电子地图与城建档案的无缝衔接,提供了电子图片档案、声像挡案的在线浏览和播放功能,实现了城建档案数据、图像、声像的有机结合,提高了城建档案的管理效率和使用率,为相同类型的城建系统提供了一定的参考作用. 相似文献

The resolution and quality of the depth map captured by depth cameras are limited due to sensor hardware limitations, which becomes a roadblock for further computer vision applications. In order to solve this problem, we propose a new method to enhance low-resolution depth maps using high-resolution color images. The structural-aware term is introduced because of the availability of structural information in color images and the assumption of identical structural features within local neighborhoods of color images and depth images captured from the same scene. We integrate the structural-aware term with color similarity and depth similarity within local neighborhoods to design a local weighting filter based on structural features. To use non-local self-similarity of images, the local weighting filter is combined with the concept of non-local means, and then a non-local weighting filter based on structural features is designed. Some experimental results show that super-resolution depth image can be reconstructed well by the process of the non-local filter and the local filter based on structural features. The proposed method can reconstruct much better high-resolution depth images compared with previously reported methods. 相似文献
