| 摘 要： | 本文基于Ｆｏｕｒｉｅｒ变换提出了场图像的等高线插值法，使场图像恢复为帧图像。通过单方向指定灰度最小波动方法寻找场图像的等高线，将等高线灰度值Ｆｏｕｒｉｅｒ变换后插值，插值后的场图像与实际帧图像比较，并与一些其它插值法比较，结果很理想。

| Abstract: | This paper proposes an coutour line interpolation about field images based on Fourier transform. This proposed approach searches after coutour lines of field images by smallest wave motion. By interpolating numbers after Fourier transform to grizzle numbers of coutour lines, comparing this results and real frame illustrates the effectiveness of the proposed approach. |
