参考曲率的双线性插值滤波
Bilinear interpolation filtering algorithm based on curvature
摘要
Abstract
In order to filter out salt and pepper noise while preserving image detail as possible, it proposes a bilinear interpolation filtering algorithm based on curvature. In view of the inherent characteristics of the bilinear interpolation of the low-pass filter, it introduces the changes of pixel values to construct the class of bilinear interpolation model. The curvature information is used to get the direction trend of adjacent pixels. It selects the direction which is closest to the original image variation to filter image using bilinear interpolation based on the curvature information. Experimental results show that this method can filter out the noise while maximizing the retention of details of images, and filtering results are better than traditional filtering algorithms.关键词
