1·While in the image normalization, the Bicubic interpolation method is used in it.

并采用双三次插值方法对图像大小归一化处理。

2·Bicubic interpolation is a classical algorithm used in spacial transformation of image such as image rotation and zooming.

双三次插值是图像空域变换的经典算法，可用于图像旋转和放缩等灰度插值。

3·In order to improve the resolution and PSNR of the obtained image without damaging its original information, the Wavelet Bicubic Interpolation Search Algorithm was proposed in the previous work.

为了在保持原始图像信息的情况下，提高图像的空间分辨率，改善图像的峰值信噪比，在前期的研究中提出了小波双三次插值搜索算法。
