Design of bicubic convolution template algorithm based on FPGA

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.
