Wavelet Transform and High-lever PDE for Image Zooming

To improve the image resolution, a new algorithm that wavelet transform and high-lever PDE for image zooming is proposed in this paper, which is based on the improving traditional wavelet transform. Compared with the traditional methods, the The effective combination of wavelet transform and high-lever PDE can keep the image´s detail characteristics. Both visual perception and experimental results have verified that the algorithm can achieve the better effective of image zooming.
