Improvement of the Space Resolution of the Optical Remote Sensing Image By the Wavelet Bi-cubic Interpolation
基于小波双三次插值提高光学遥感图像空间分辨率的研究

In order to preserve the original information of the optical remote sensing image, to improve its space resolution possibly high, and to favorably observe and analyze its detail information, the wavelet bi cubic interpolation was proposed in this paper. The experiment result proved that the image processed by the wavelet bi cubic interpolation had a relative higher peak signal noise ratio and better image detail information than the images processed by the wavelet scale function Interpolation and the wavelet bi linear interpolation. It is proved that the wavelet bi cubic interpolation is an effect algorithm to improve the space resolution of the optical remote sensing image.
