This paper presents a design of two-point interpolation filters. The proposed design method provides novel interpolation kernels including trigonometric polynomials and it is considered to be a generalized version of the standard linear interpolation. Also, the proposed design method gives us an efficient hardware implementation by adding our modifying functions to the linear interpolation. Experimental results indicate that the proposed kernels outperform the existing kernels.
