Abstract

Padding the boundary is the first step in image filtering. If not appropriately handled, it often cause serious artifacts and losing information. In this paper an optimized boundary padding method is proposed to solve this problem. We analyze the pixel values near the boundary, calculate the gradient of the pixels, and pad the input image with a center symmetric padding method. Consequently, the details of the boundary will be preserved, and the number of unexpected noise will be suppressed as much as possible. We demonstrate that the center symmetric padding method is more effective than the traditional border handling methods in some computer vision applications.
