摘　　要：为了能在硬件上实现高质量、高效果的视频图像缩放、旋转等,文章研究分析了双三次插值算法的实现,对双三次插值计算进行离散化,得到相应的计算模板,简化计算过程。提出了一种在FPGA上实现双三次卷积模板算法的方法。实验结果表明:该算法的缩放效果优于双线性插值算法,略低于双三次插值算法,但计算性能上明显高于双三次插值算法。双三次卷积模板插值算法是一种能够在有限的资源上实现较好效果的插值算法。In order to achieve high-quality, high-effect on the hardware video scaling, rotation, and so on,this paper analyzes the realization of bi-cubic interpolation algorithm,makes the bicubic interpolation discrete and infer templates,which make the calculation process simplify.This paper proposed a method to achieve bicubic convolution template algorithm in FPGA. Experimental results show that the algorithm is superior zoom effect bilinear interpolation algorithm, slightly lower than the bicubic interpolation algorithm, but the computational performance was significantly higher than bicubic interpolation algorithm. So bicubic convolution algorithm is a template to achieve better results in the limited resources interpolation algorithm.
