摘要
文章首先分析和研究了传统的图像插值算法——基于边缘的图像插值算法和不基于边缘的图像缩放算法的基础上,然后将一种优化的双线性插值算法应用在图像缩放引擎中;其次,在缩放引擎的硬件实现上,采用了两次缩放内核的结构设计了各个子模块电路,并用Modelsim对各个子模块进行了仿真;最后,在Altera公司的FPGA开发板上进行了实现。实验结果表明所设计的定标器显示效果良好。
Firstly, the traditional image interpolation algorithm--based on the edge and not based on the edge, are analyzed and researched. And the optimized bilinear interpolation algorithm is used in image scaling engine. During the hardware realization, two zoom kernel structures are adopted. Each submodule is simulated by Modelsim and verified by using FPGA development board of Altera. The experiment shows that this design has very good display effect.
