Abstract: General restoring algorithms based on PDE could lose local feature and degenerate reading and understanding on image. In this paper, we recommend a technique to better preserve local feature by PDE and Gabor (PG) in image restoring processes. It borrows ideas from Gabor Wavelet Transformation (GWT) and is achieved by splitting the image regions which comprise ordinary regions and preserved regions. In order to preserve the regions of textures ｏｒ certain details, we take advantage of GWT to search and write down these regions. Then, we may employ the algorithm PDE-based to dispose them respectively. Our results show these regions, which are preserved, retain the characteristics of original image.
