介绍了一种基于图像的双三次线性插值缩放算法的设计方法,并通过FPGA验证了设计的可行性.重点讨论了视频缩放的插值算法,对两种实现方法在硬件资源利用率及实施效率方面进行了比较并论证了块状插值实现方法的优越性.最终设计实现了高分辨率实时视频图像的缩放.
An interpolation algorithm used in image zooming was introduced and a real-time monitoring image zooming based on FPGA was presented. The algorithm was discussed. Both of the implementations were compared to verify in hardware resource utilization and efficiency, and demonstrated the superiority of the block interpolation. The system is proved to be stable when it is applied to the monitoring image zooming with real-time and high-resolution.
