1) video vectorization
视频矢量化
2) vector video
矢量视频
1.
Circuit receives vector video signals and standard PAL video signals are overlayed and stored to dual-port RAM by embedded NIOS ⅡCPU.
嵌入式NIOSⅡ CPU控制电路接收矢量视频信号及标准PAL制视频信号,使其相叠加后存储于双端口RAM,上位机通过PXI总线接口将双端口RAM中数字视频信号采集至内存,并通过软件将叠加后的视频信息回放。
3) vector field visualization
矢量场可视化
1.
A new planar vector field visualization method was discussed,it utilized the characteristic that the streamlines are approximately parallel in local vector field region,extend-ed the range of seed point,thus streamline can cover more adjacent points,and averaged different streamlines so image was smoother.
矢量场可视化是科学计算可视化的重要组成部分。
2.
Comparing with the traditional methods,this method has higher precision and can get similar image with FastLIC ,it is still used in vector field visualization.
基于OpenGL实现了科学计算可视化中传统的线积分卷积算法,因OpenGL能达到的数据精度较高,此方法取得了和快速线积分卷积算法相似的效果,在矢量场可视化中仍有重要的实用价值。
3.
Line Integral Convolution (LIC) method is a powerful technique for representing directional information in vector field visualization.
