| Abstract(in English) | Edge-preserving smoothing filter smoothes the textures while preserving the information of sharp edges. In image processing, this filter is used as fundamental process of many applications. In this paper, we propose a new approach for edge-preserving smoothing filter. Our method uses 2D filter like as bilateral filter to smooth images and also we applied indicator function to restrict the range of filtered pixels for edge-preserving. Defining the indicator function, we recalculate the distance between each pixels by using the information of edges and only the nearby pixels in the reconstructed domain are used for smoothing. Since our method constrain the pixel used for the filtering, its implementation is quite fast. We demonstrate the usefulness of our new edge-preserving smoothing method for various kinds of applications. |
