利用小波双线性超分辨率重建算法得到的重建图像会出现低、高频系数不匹配的现象，从而使得到的高分辨率图像灰度偏移。本文对该方法进行了改进，并引入局部适应插值得到更为理想的重建算法。即小波与局部适应插值结合算法。-The reconstructed image obtained by wavelet bilinear super- resolution reconstruction algorithm will appear the phenomenon of low and high frequency coefficients mismatch, which makes the high- resolution image gray- scale shift. In this paper, the method is improved, and the local adaptive interpolation is introduced to obtain a more ideal reconstruction algorithm. A Wavelet and Local Adaptive Interpolation Algorithm.
