Local Laplacian Filters and some extensions

The Laplacian pyramid was always used for image analysis.However, the Laplacian pyramid could also be used for edge-aware image processing.To get successful results, this method spent much less time than most of other methods such as anisotropic diffusion, neighborhood filtering, and specialized wavelet bases.This method was based on the way of iteration and process each pixel again and again.The more times this method computed the image in the iteration, the better the result was.While there was a disadvantage of this method: there existed over enhancement in some areas.To this drawback, My study improved this method, which led to image distortion.Besides, my method made it possible to process video.My research also found that this method could be used to remove haze in the image.
