摘　　要：将插值小波算法和自适应积分方法相结合,提出了一种用于偏微分方程求解的新方法—插值小波自适应精细积分法。实现了由该种方法构造的小波形函数的快速算法,有效的提高了计算效率。利用自适应多层插值小波算法对热传导方程进行求解,实现了对图像的降噪,实验结果表明了该方法用于图像降噪的有效性。A new method for image processing which use the partial differential equations （PDEs） to solve efficiency is proposed in this paper by combining the wavelet adaptive multilevel interpolation method with the precise integration method （PIM）. The method is called interpolation wavelets adaptive precise integration method. Therefore wavelet fast calculation of the function is achieved,and computational efficiency is improved effectively . And then this new method is used in solving the heat conduction equations,and image de-noising is achieved,which shows the corrective and the efficiency of the proposed method.
